OPINION OF THE COURT

MEMORANDUM.

In People v Argyris and People v DiSalvo, the orders of the Appellate Division should be affirmed. In People v Johnson, the order of County Court should be reversed, the suppression motion granted and the accusatory instrument dismissed.

Regardless of whether we apply a totality of the circumstances test or the Aguilar-Spinelli standard (see Spinelli v United States, 393 U.S. 410 [1969]; Aguilar v Texas, 378 U.S. 108 [1964]), there is record support for the lower courts' findings that the stops were lawful in People v Argyris and People v DiSalvo. The police had reasonable suspicion to stop defendants' vehicle based on the contents of a 911 call from an anonymous individual and the confirmatory observations of the police. Specifically, because sufficient information in the record supports the lower courts' determination that the tip was reliable under the totality of the circumstances, satisfied the two-pronged Aguilar-Spinelli test for the reliability of hearsay tips in this particular context and contained sufficient information about defendants' unlawful possession of a weapon to create reasonable suspicion, the lawfulness of the stop of defendants' vehicle is beyond further review. Furthermore, under these circumstances, the absence of predictive information in the tip was not fatal to its reliability (compare People v Moore, 6 N.Y.3d 496, 499 [2006], with Navarette v California, 572 US ___, ___, 134 S.Ct. 1683, 1688-1692 [2014]). On this record, the lower courts did not err in concluding that the police's other actions were lawful (see People v Brnja, 50 N.Y.2d 366, 372 [1980]).

In People v Johnson, whether evaluated in light of the totality of the circumstances or under the Aguilar-Spinelli framework, the reliability of the tip was not established. The caller's cursory allegation that the driver of the car was either sick or intoxicated, without more, did not supply the sheriff's deputy who stopped the car with reasonable suspicion that defendant was driving while intoxicated (see generally People v DeBour [La Pene], 40 N.Y.2d 210, 225 [1976]; cf. Navarette, 572 US at ___, 134 S Ct at 1690-1692). Although the deputy observed defendant commit a minor traffic infraction, this did not authorize the vehicle stop because he was outside his geographical jurisdiction at the time of the infraction (see CPL 140.10 [2] [a]), and defendant's actions in committing the violation did not elevate the deputy's suspicion sufficiently to justify the stop of defendant's car. The issue of whether suppression should be denied on the theory that the deputy's violation of the statutory limits on his jurisdiction does not warrant suppression is not before us.

SMITH, J. (concurring).

Four Judges agree that we should affirm in the first two of these cases and reverse in the third, but we disagree on the rationale. The issue that divides us is whether to apply the Aguilar-Spinelli test to stops that require only reasonable suspicion. We have never done so before, and I think we should not do so now, because the Aguilar-Spinelli test needlessly complicates and confuses the analysis of reasonable suspicion issues.

Under the rule established by Aguilar v Texas (378 U.S. 108 [1964]) and Spinelli v United States (393 U.S. 410 [1969]), whether information supplied by an informant to the police is sufficient to provide probable cause for a search or a seizure is decided by the application of a two-pronged test: Courts must evaluate both the basis of the informant's knowledge and the reliability or veracity of the informant himself (see People v Johnson, 66 N.Y.2d 398, 402-403 [1985]). The United States Supreme Court, finding the test too rigid, abandoned it in Illinois v Gates (462 U.S. 213 [1983]) in favor of "totality-of-the-circumstances analysis" (id. at 233) — a polysyllabic way of saying that courts look at all the facts and see if they add up to probable cause. But our Court has rejected the Gates approach and continues to apply the Aguilar-Spinelli rule to probable cause issues (Johnson, 66 NY2d at 406-407; People v Griminger, 71 N.Y.2d 635, 639 [1988]).

In applying the Aguilar-Spinelli rule, we have moderated the rigidity of the two-pronged test by holding that evidence corroborating the informant's statements may, in some cases, satisfy either the basis-of-knowledge or the veracity/reliability prong (People v Elwell, 50 N.Y.2d 231, 234-235 [1980] [basis-of-knowledge prong may be satisfied only by "confirmation of sufficient details suggestive of or directly related to the criminal activity informed about"]; People v DiFalco, 80 N.Y.2d 693, 695 [1993] ["the veracity component ... may ... be satisfied by police corroboration of details that are not, if taken separately, suggestive of criminal activity"]). To the extent that such evidence — which does not directly prove either the basis of the informant's knowledge or his truthfulness — may satisfy either prong, the two prongs tend to merge, and the Aguilar-Spinelli rule begins to resemble the totality-of-the-circumstances test.

While we have attenuated the Aguilar-Spinelli rule in the probable cause context, we have not, so far as I know, even applied it before today where the issue was reasonable suspicion. We have decided several reasonable suspicion cases without any reference to the Aguilar-Spinelli rule (People v Moore, 6 N.Y.3d 496 [2006]; People v Salaman, 71 N.Y.2d 869 [1988]; People v Benjamin, 51 N.Y.2d 267 [1980]; People v Stewart, 41 N.Y.2d 65 [1976]). In People v Landy (59 N.Y.2d 369, 375-377 [1983]), we relied on the Aguilar-Spinelli rule in concluding that probable cause was lacking, but then left that rule unmentioned in upholding the search and arrest on the ground that a finding of reasonable suspicion was supported by the record (see also People v Chase, 85 N.Y.2d 493, 501 [1995] [holding probable cause to be lacking on Aguilar-Spinelli grounds; remitting the case, without further mention of Aguilar-Spinelli, for determination of the reasonable suspicion issue]).

Today, two of my colleagues would extend the Aguilar-Spinelli standard "to the determination of the legality of investigatory stops precipitated by anonymous hearsay tips" (concurring op of Abdus-Salaam, J. at 1143-1144). This would mean, presumably, that in such cases a court must find that a reasonable person could suspect — though not necessarily believe it probable — that the informant had an adequate basis of knowledge and was a credible or reliable source. The second determination, the so-called "veracity" prong, seems especially hard to make in anonymous tip cases: there are obvious problems in evaluating the veracity of an informant when the police do not know who the informant is.

Judge Abdus-Salaam's opinion overcomes this and any other problems that the Aguilar-Spinelli test may present with a minute analysis of the evidence in these cases. In Argyris and DiSalvo, Judge Abdus-Salaam would find both prongs of the test to be satisfied, relying, as to both prongs, on the content of the recorded 911 call. In Johnson, she would find that the anonymous call did not satisfy the basis-of-knowledge prong, and that no corroborating evidence supplies the deficiency; she does not discuss the veracity prong in deciding Johnson, but she could easily reach a similar conclusion on that issue for essentially the same reasons. I generally agree with the analysis of the facts in Judge Abdus-Salaam's opinion, but I do not see what is gained by dividing that analysis into two prongs. Using a totality-of-the-circumstances approach would lead us, more quickly and with less complexity, to the same place.

ABDUS-SALAAM, J. (concurring).

In considering the legality of police searches and seizures instigated by hearsay information under article I, § 12 of the Constitution of the State of New York, we have adhered to the Supreme Court's mid-twentieth-century jurisprudence on hearsay tips as laid out in Aguilar v Texas (378 U.S. 108 [1964]) and Spinelli v United States (393 U.S. 410 [1969]). Thus, we have held that hearsay information cannot provide a police officer with probable cause to arrest an individual unless the hearsay report reveals a reliable basis for the informant's knowledge and shows that the informant is generally credible (see People v Johnson, 66 N.Y.2d 398, 406-407 [1985]). In holding that, under any relevant legal standard, the tip in People v Argyris and People v DiSalvo bears legally sufficient indicia of reliability and the tip in People v Johnson does not (see majority mem at 1140-1141), the Court does not retreat from this state constitutional tradition, and therefore I join the Court's memorandum opinion in full.

I write separately to suggest further guidance on the legal standards that, in my opinion, should apply to the determination of the legality of investigatory stops recipitated by anonymous hearsay tips. In my view, courts should apply the Aguilar-Spinelli standard to determine the legality of investigatory stops precipitated by anonymous hearsay tips. Accordingly, I would hold that the police cannot physically seize an individual based solely on an anonymous hearsay tip, regardless of whether they seek to effect an arrest or a brief investigatory stop, unless the tip satisfies the veracity and basis-of-knowledge prongs of the Aguilar-Spinelli test. Furthermore, I would conclude that the determination of whether a tip provides the police with probable cause or reasonable suspicion depends on the quality of the tip's description of the crime itself, as opposed to its statements regarding the suspect's physical appearance and non-criminal conduct.

I. People v Argyris and People v DiSalvo

At about 2:15 p.m. on July 19, 2007, an unidentified man called 911. The man told the 911 operator that he was near a building at New Town Avenue and 31st Street in Astoria, Queens, and that, as he had come out of the building, he had seen someone with a gun. Specifically, the man said, "I saw a black mustang, brand new black mustang with like four guys and I saw one of them put in a big gun in the back of the car." The caller reported the license plate number of the black Mustang. The caller told the operator that the car had "just [gone]" down the block to 28th Street and then turned right onto that street heading toward Astoria Boulevard. According to the caller, a grey van had been accompanying the car. When the operator interrupted the caller and asked whether he wanted to provide his name and telephone number, the caller replied, "No I don't really want to, I just saw something and I say something like they say."

When questioned about the men's appearance, the caller said that they were "tall big bully white guys." The operator inquired about the men's clothing, and the caller said that he did not know what they were wearing. He did state, "I'm sorry... well, when the guy was putting the gun on the back of the car that I saw him [sic] ... so I just made, I play stupid and I went right into my car." The operator asked whether the caller would wait for the police to arrive, and he responded, "Well, uh, do you want me to wait around for them?" The operator stated, "It's up to you." The caller said, "I don't really have to," adding, "OK?" The operator replied, "Alright," and the call ended. The entire 911 call was recorded.

A few minutes later, several New York City police officers on vehicular patrol in separate cars, including Sergeant Louis Bauso, Officer Michael Castelli and Officer Kashim Valles, received a radio run reporting the details contained in the 911 call. Bauso drove to the area described in the call and looked for the black Mustang, but he did not find it. At around 2:30 p.m., Castelli spotted a black Mustang and a grey van on 31st Street. The Mustang had the license plate number reported by the 911 caller. Castelli and his partner decided to follow the vehicles, and Castelli's partner sent a radio transmission stating that they were doing so. The record on appeal does not reveal whether any of the other officers received Castelli's partner's radio run.

Around that time, Sergeant Bauso saw the Mustang and the van at a traffic light, and he pulled over at a bus stop and got out of his car to get a better look at the license plate number on the Mustang. After seeing that the license plate number matched the 911 caller's description of it, Bauso allegedly pointed at the Mustang and called out, "Pull over." The Mustang continued driving, and at a nearby intersection at 31st Street, the Mustang and the van went in separate directions. Bauso got back in his car and pursued the Mustang.

Meanwhile, Officer Valles saw the Mustang drive toward him and then turn onto 31st Street. Valles drove after the Mustang, and soon thereafter, he stopped it by using his car to cut it off. Valles called for backup, and he got out of his car and pointed his gun at the Mustang. Sergeant Bauso, his partner and about six other officers arrived, and as the backup officers trained their guns on the Mustang, Valles holstered his weapon and directed the occupants of the Mustang to exit the car.

Defendant John DiSalvo exited from the front passenger seat of the Mustang, and Officer Valles observed that DiSalvo had a gun in his waistband. Valles ordered DiSalvo to put his hands on the Mustang, and after DiSalvo complied, Valles handcuffed DiSalvo and searched him, recovering the gun and some cash. Valles then continued to order the occupants of the Mustang to exit one by one, and he handcuffed and searched each one. After the driver was searched, defendant Costandino Argyris emerged from the backseat wearing a bulletproof vest, which was visible underneath his sweatshirt. When Valles searched Argyris, he recovered a metal and leather club, as well as a switchblade, from Argyris's person. Upon searching the car, Valles found a loaded .38 caliber handgun under the driver's seat and a box of 9 millimeter ammunition on the backseat.1

Following their indictment on various weapons-related charges, defendants moved to suppress the items recovered from their persons and the Mustang as the fruits of an unlawful seizure. At a hearing held on defendants' suppression motion, the officers testified to the facts set forth above, and the People presented the audio recording of the 911 call. Following the presentation of the evidence, Supreme Court initially issued a written decision granting defendants' suppression motion, reasoning that, under the U.S. Supreme Court's decision in Florida v J.L. (529 U.S. 266 [2000]), the 911 caller's failure to predict defendants' future actions rendered his assertions too unreliable to support the stop of the car.

Subsequently, the People moved for reargument and reconsideration of the suppression decision. The court issued a written decision granting the People's motion and, upon reconsideration, vacating its prior suppression decision and denying defendants' motion to suppress the physical evidence. Discussing the relevant legal framework, the court noted that an anonymous informant's hearsay report of criminal activity may give rise to probable cause justifying an arrest if the report satisfies the two prongs of the Aguilar-Spinelli test. The court further observed that, because a tip that satisfies the Aguilar-Spinelli standard may support an arrest, such a tip may also be reliable enough to create reasonable suspicion justifying the lesser intrusion of an investigatory stop.

Under those legal standards, the court found that the 911 caller's statements here were reliable enough to authorize Officer Valles to stop defendants' car. The court determined that, because the 911 caller had provided an accurate description of the Mustang, the van and their location, his report established his credibility and thereby met the veracity prong of the Aguilar-Spinelli test. And, the court concluded, the caller's statements demonstrated the basis of the caller's knowledge, in satisfaction of the basis-of-knowledge prong of the Aguilar-Spinelli test, because the caller declared that he had personally seen the occupants of the Mustang place a large gun therein. The court also distinguished Florida v J.L. from this case. Additionally, the court rejected defendants' claim that the officers had acted unreasonably in surrounding the Mustang and ordering defendants out of the car at gunpoint. In the court's view, the officers had taken those lawful precautions out of a reasonable concern for their safety. Thus, the court denied defendants' suppression motion in its entirety.

Thereafter, defendant Argyris pleaded guilty to two counts of criminal possession of a weapon in the second degree (see Penal Law § 265.03 [1] [b]), one count of criminal possession of a weapon in the fourth degree (see Penal Law § 265.01) and one count of unlawful possession of pistol ammunition (see Administrative Code of City of NY § 10-131 [i] [3]), and he was sentenced to an aggregate determinate prison term of 3½ years. Defendant DiSalvo pleaded guilty to four counts of criminal possession of a weapon in the second degree (see Penal Law § 265.03 [1] [b]; [3]), three counts of criminal possession of a weapon in the third degree (see Penal Law § 265.02 [1]) and one count of unlawful possession of pistol ammunition (see Administrative Code of City of NY § 10-131 [i] [3]), and he was sentenced, as a second felony offender, to an aggregate determinate prison term of six years, to be followed by five years of postrelease supervision. Defendants appealed from the respective judgments against them, challenging Supreme Court's suppression ruling.

The Appellate Division, Second Department, issued separate decisions and orders affirming the judgments in each case (see People v DiSalvo, 99 A.D.3d 811 [2d Dept 2012]; People v Argyris, 99 A.D.3d 808, 808-811 [2d Dept 2012]). In People v Argyris, the Appellate Division first concluded that "[t]he Aguilar-Spinelli test ... need not be satisfied where [as here] the necessary predicate for justifying the police action under review is the less demanding standard of reasonable suspicion" (99 AD3d at 810 [internal quotation marks and citations omitted]). The court determined that Officer Valles had the requisite reasonable suspicion to stop the Mustang because "the report of the 911 caller, which was based on the contemporaneous observation of conduct that was not concealed, was sufficiently corroborated to provide reasonable suspicion for the stop" (see id. [internal quotation marks and citations omitted]). Furthermore, the court decided that the police had otherwise acted lawfully when they ordered defendants out of the car at gunpoint, and because the officers properly obtained the relevant evidence from defendants and their car, Supreme Court had correctly denied their suppression motion and accepted their guilty pleas (see id. at 810-811).

In a separate decision and order citing its decision in People v Argyris, the Appellate Division affirmed the judgment in People v DiSalvo and remitted that case to Supreme Court for proceedings regarding defendant DiSalvo's bail under CPL 460.50 (5) (see DiSalvo, 99 AD3d at 811-812). A Judge of this Court granted defendants leave to appeal from the Appellate Division's orders (People v Argyris, 21 N.Y.3d 1013 [2013]; People v DiSalvo, 21 N.Y.3d 1015 [2013]).

People v Johnson

At about 9:22 p.m. on October 1, 2011, a police dispatcher radioed Yates County Sheriff's Deputy Arlyn Cunningham, Jr. and told him that "a civilian had called 911 and stated that she believed that the driver" of a blue BMW with a particular license plate number was "sick or intoxicated" at the intersection of Route 245 and Sunnyside Road in the Town of Italy, which is near the border between Yates County and Ontario County. As far as the record shows, the 911 call was not recorded in any way.

Deputy Cunningham, in his marked patrol car, started driving south on Route 245 in search of the BMW. Cunningham drove to the intersection referenced in the 911 call, but he did not see the BMW. After "decid[ing] which was the most probable route of travel" for the BMW, Cunningham continued driving south on Route 245 and crossed into Ontario County.

Deputy Cunningham entered the Town of Naples, and he stopped at a stop sign at the intersection of Route 245 and Route 21. At the stop sign, he saw the blue BMW with the license plate number described in the 911 caller's report. The BMW turned left onto Route 21. As Cunningham followed the BMW, that vehicle went a short distance and then made a "hasty" right turn onto Tobey Street. In particular, the BMW activated its turn signal at the last moment, made a wide right turn, went briefly into the lane of Tobey Street used by oncoming traffic and then quickly entered the correct lane. Cunningham turned onto Tobey Street and activated his emergency lights and siren. As Cunningham would later testify at the suppression hearing in this case, he pulled over the BMW based on his suspicion that the driver was driving while intoxicated and also upon his observation of the driver committing a traffic violation. However, Cunningham knew that he could not arrest the driver for the traffic violation because relevant statutes prevented him from arresting someone for a traffic violation outside of Yates County (see CPL 140.10 [2] [a]; cf. CPL 140.10 [1] [b]).

Deputy Cunningham approached the BMW, and he saw defendant, Dr. Eric Johnson, in the driver's seat, accompanied by a female in the passenger's seat. Cunningham noticed that defendant had glassy eyes, a fixed gaze and breath that smelled strongly of alcohol. Cunningham asked defendant to divulge his personal identifying information and his activities that evening. In response, defendant fumbled through his wallet for his driver's license and slurred his words, further convincing Cunningham that he was intoxicated. Cunningham radioed the dispatcher, reported that he had stopped defendant's car and requested that an Ontario County Deputy come to the scene to assist him.

About half an hour later, Ontario County Sheriff's Deputy David Drake responded to the scene, where he also saw defendant exhibiting telltale signs of intoxication. Drake had defendant perform three field sobriety tests, all of which defendant failed. Concluding that defendant had been driving while intoxicated, Drake arrested defendant on that charge and transported him to the station house. There, defendant agreed to take a breath test to measure his blood alcohol content, and the test results revealed that defendant had a blood alcohol content of 0.15% by volume — nearly twice the legal threshold for driving while intoxicated under Vehicle and Traffic Law § 1192 (2).

After being charged with several counts of driving while intoxicated, defendant moved to suppress his statements to the police and the results of the breath test on the ground that such evidence was the fruit of an unlawful vehicle stop unsupported by reasonable suspicion or probable cause. At a suppression hearing in Town Court, Deputies Cunningham and Drake testified to the facts described above.

Following the hearing, Town Court issued a written decision denying defendant's suppression motion in its entirety. The court concluded that Cunningham had properly stopped and, with the aid of Deputy Drake, lawfully arrested defendant. According to the court, the 911 caller's tip about a possible incident of driving while intoxicated had authorized Cunningham to follow and "close in" on defendant's car. Once Cunningham saw defendant make a wide right turn, the court opined, Cunningham had "justification for the stop and investigation of a possible crime of DWI." And, given that Cunningham saw defendant exhibit signs of intoxication upon stopping the car, Cunningham and Drake had the right to arrest defendant for driving while intoxicated. Consequently, the court ruled, defendant's statements and the breath test results had been lawfully obtained pursuant to a valid stop and arrest.

Defendant moved for reargument, which the court denied. Subsequently, defendant pleaded guilty to a misdemeanor count of driving while intoxicated (see Vehicle and Traffic Law § 1192 [3]), and he was sentenced to a six-month suspension of his driver's license, a conditional discharge and various fines. Defendant appealed.

County Court affirmed the judgment. County Court decided that Deputy Cunningham had no authority to stop defendant for the traffic violation of making a wide right turn, saying, "Inasmuch as the deputy who [had] stopped the vehicle, Deputy Cunningham, did not view the defendant drive his vehicle in Yates County, ... Deputy Cunningham was without authority to stop the defendant for a traffic infraction." Nonetheless, County Court determined that the 911 caller's tip had given Cunningham reasonable suspicion that defendant had been driving while intoxicated, thereby authorizing Cunningham to stop defendant's car for that crime even in another county. Specifically, the court decided that, because the tip had accurately identified defendant's car and approximate location, it was reliable enough to establish reasonable suspicion, especially when coupled with Cunningham's personal observation of defendant committing a traffic violation. Thus, the court concluded that defendant's suppression motion had been properly denied and affirmed the judgment. A Judge of this Court granted defendant leave to appeal (23 N.Y.3d 1021 [2014]).

II

A

To be reliable enough to establish probable cause for an arrest as a matter of state constitutional law, an anonymous hearsay informant's report of criminal activity must: (1) provide sufficiently detailed information to indicate the informant's reliability as an informant, or in other words, his or her veracity; and (2) convey information showing a reliable basis for the informant's knowledge of the reported illegal activity (see People v Edwards, 95 N.Y.2d 486, 495 [2000]; Johnson, 66 NY2d at 406-407; People v Elwell, 50 N.Y.2d 231, 236-237 [1980]; People v West, 44 N.Y.2d 656, 657 [1978]; see also Spinelli, 393 US at 412-413; Aguilar, 378 US at 114-115). In adopting this rule under the State Constitution, we have refused to follow the U.S. Supreme Court's decision in Illinois v Gates (462 U.S. 213 [1983]), which holds that the two prongs of the Aguilar-Spinelli test are merely "relevant considerations in the totality-of-the-circumstances analysis that traditionally has guided probablecause determinations" under the Fourth Amendment (Gates, 462 US at 233; contrast Johnson, 66 NY2d at 406-407).

Just as reliable hearsay can supply the police with probable cause, such hearsay can give rise to reasonable suspicion, which is the lesser level of suspicion required to authorize an investigatory stop of a person or a moving car under the four-tiered framework of People v De Bour (40 N.Y.2d 210 [1976]) — also sometimes called a level-three stop under De Bour or, in federal constitutional parlance, a Terry stop (see Navarette v California, 572 US ___, ___, 134 S.Ct. 1683, 1687-1688 [2014]; Adams v Williams, 407 U.S. 143, 147 [1972]; Terry v Ohio, 392 U.S. 1, 20-27 [1968]; People v Landy, 59 N.Y.2d 369, 376 [1983]). In the past, we interpreted the State Constitution to permit a level-three stop based on a hearsay report that did not meet both prongs of the Aguilar-Spinelli standard for reliability (see People v Salaman, 71 N.Y.2d 869, 870 [1988]; Landy, 59 NY2d at 376). Even then, we did not retreat from our general admonition against police reliance on unreliable anonymous tips, noting that hearsay information of that kind was "the weakest sort" of support for a forcible detention (De Bour, 40 NY2d at 224). Subsequent developments in federal constitutional jurisprudence cast significant doubt on our prior holdings that "unsubstantiated hearsay" reports of criminality are reliable enough to authorize the police to conduct a level-three stop supported by reasonable suspicion (Landy, 59 NY2d at 376).

The relevant changes in federal law originated in Alabama v White (496 U.S. 325 [1990]), in which the U.S. Supreme Court explained that the police cannot detain someone based on completely uncorroborated hearsay and may only act on tips bearing significant indicia of reliability. In that case, an anonymous hearsay tip apprised the police of the movements of a suspect in detail and alleged that the suspect would have drugs in an attaché case (see White, 496 US at 327). Although the police did not see the case upon spotting the suspect, they followed her and stopped her before she reached the destination reported in the tip (see id.). The police then recovered a case of drugs from the suspect's car (see id.). The Supreme Court upheld the legality of the stop, finding that this was a "close case" but that the tip bore sufficient "indicia of reliability" to give the police reasonable suspicion to stop the suspect's car (id. at 327-332). The Court found it particularly significant that the tip predicted the suspect's movements, as such predictive information could only have come from a person with reliable insider knowledge of the suspect's affairs (see id. at 331-332). Accordingly, under White, an anonymous tip cannot support the stop of a car unless it bears sufficient indicia of reliability under the totality of the circumstances, and one important indicium of reliability is a tip's prediction of the future behavior of the suspect.

Subsequently, in Florida v J.L., the Supreme Court invalidated a stop predicated upon a bare-bones tip while suggesting that not all tips need the sort of predictive information discussed in White to be reliable. In J.L., an anonymous caller, whose call was not recorded, told the police that "a young black male standing at a particular bus stop and wearing a plaid shirt was carrying a gun" (J.L., 529 US at 268). Based on the tip, the police stopped 15-year-old J.L. merely because he matched the description, and they recovered a gun from him (see id.). They also frisked two other men who were standing near him, despite the fact that the tip had not mentioned those individuals (see id.). The Supreme Court held that the stop was illegal because "[t]he tip in the instant case lacked the moderate indicia of reliability present in White and essential to the Court's decision in that case," and hence the tip did not provide the police with reasonable suspicion (id. at 271). At the same time, the Court observed that the absence of predictive information was not the only source of the deficiency in the tip, as the tip was also unreliable because the "unknown, unaccountable informant ... neither explained how he knew about the gun nor supplied any basis for believing he had inside information about J.L." (id. [emphasis added]). In a concurrence, Justice Kennedy and Chief Justice Rehnquist reenforced this point, suggesting that indicia of reliability such as recording of an anonymous 911 call might allow the police to stop a suspect, regardless of the presence or absence of predictive information (see id. at 274-276 [Kennedy, J., concurring]).

Given White's and J.L.'s reliability requirements for anonymous tips underlying Terry stops, we have subsequently abandoned certain aspects of our prior precedent permitting a stop based on "unsubstantiated hearsay" (Landy, 59 NY2d at 376), acting on constraint of federal constitutional law. For example, in consolidated appeals in People v William II and People v Rodriguez, we followed J.L.'s stricter approach to the reliability analysis under the Federal Constitution, invalidating the stops in both cases based on tips that, in our view, were not sufficiently reliable under J.L.'s mandate (see People v William II, 98 N.Y.2d 93, 98-100 [2002]). Specifically, we decided that, since the tips lacked both predictive information and any indication that the informants had firsthand knowledge of the relevant crimes, the tips were unreliable "[u]nder the requirements of Florida v J.L." (id. at 99). Thus, in William II, we necessarily rejected certain facets of our prior decisions that established a low threshold for reliability in the reasonable suspicion context. In particular, that case stands for the proposition that, under the Fourth Amendment, an anonymous tip is unreliable if it is not made via 911, does not include a statement of the informant's firsthand knowledge of the contents of the report and does not provide any predictive information. In reaching that conclusion, we did not conduct any independent state constitutional analysis of the reliability of the tips at issue in William II, instead relying exclusively on U.S. Supreme Court precedent.

More recently, in People v Moore (6 N.Y.3d 496 [2006]), we again evaluated the reliability of an anonymous tip under the Federal Constitution and concluded, in part based on the lack of predictive information in the tip before us, that the tip was not sufficiently trustworthy to give rise to reasonable suspicion (see Moore, 6 NY3d at 497-501). In doing so, we relied on William II's interpretation of J.L., holding that the tip at issue, which did not feature any predictive information, lacked any suggestion of the informant's firsthand knowledge of the crime and was contradicted by the officers' observations at the scene, was not sufficiently reliable to authorize the police to conduct an investigatory stop of the suspect (see id. at 498-501).

In Moore, we also said that "[a]n anonymous tip cannot provide reasonable suspicion to justify a seizure, except where that tip contains predictive information — such as information suggestive of criminal behavior — so that the police can test the reliability of the tip" (id. at 499 [emphasis added]). However, that pronouncement was not essential to our holding. In deciding that the tip implicating the suspect was unreliable, rather than relying on the absence of predictive information, we cited numerous other aspects of the tip that called its credibility into doubt. Thus, our comment about the possible necessity of predictive information was dicta based on our understanding of federal constitutional law at the time, and we did not establish a predictive information requirement independently rooted in the State Constitution.

After our decision in Moore, the U.S. Supreme Court explained in Navarette v California that predictive information is not the sine qua non for the reliability of an anonymous hearsay tip under the Federal Constitution. In Navarette, a police dispatch team from one county in California relayed the contents of a 911 call to a dispatch team in another county (see Navarette, 572 US at ___, 134 S Ct at 1686). The reporting dispatchers described the call to the other team as follows: "[s]howing southbound Highway 1 at mile marker 88, Silver Ford 150 pickup. Plate of 8-David-94925. Ran the reporting party off the roadway and was last seen approximately five [minutes] ago" (572 US at ___, 134 S Ct at 1686-1687). The receiving dispatch team, in turn, transmitted the information to highway patrol officers (see 572 US at ___, 134 S Ct at 1687). Roughly 10 minutes later, a highway patrol officer saw the above-described truck near mile marker 69 — not far from marker 88 referenced in the 911 report (see id.). About five minutes later, the officer pulled over the truck, and another officer joined him at the scene (see id.). When the officers approached the truck, they smelled marijuana and, upon searching the vehicle, recovered 30 pounds of that substance (see id.). The officers arrested Lorenzo and Jose Navarette, who were the driver and passenger in the truck (see id.).

By a vote of five to four, the Supreme Court affirmed the California courts' decisions denying suppression of the drugs (see 572 US at ___, 134 S Ct at 1686-1692). The Court concluded that the 911 call, as conveyed via the dispatchers, had provided the patrol officers with reasonable suspicion supporting their stop of the Navarettes' truck because, "[e]ven assuming for present purposes that the 911 call was anonymous, ... the call bore adequate indicia of reliability for the officer to credit the caller's account" of events (572 US at ___, 134 S Ct at 1688). In the Court's view, "[b]y reporting that she had been run off the road by a specific vehicle — a silver Ford F-150 pickup, license plate 8D94925 — the caller necessarily [had] claimed eyewitness knowledge of the alleged dangerous driving," which "len[t] significant support to the tip's reliability" (572 US at ___, 134 S Ct at 1689). The Court distinguished J.L. from the case before the Court on the basis that, unlike the tipster in J.L. who "provided no basis for concluding that [he] had actually seen the gun," the 911 caller in this case evidently had personally witnessed the truck driver's unlawful drunk driving (id.).

The Court further determined that the tip contained information showing that the caller was telling the truth, including the contemporaneous nature of the tipster's report and the officers' success in corroborating the report's description of the truck's appearance and location within a short time of receiving the dispatch about it (see id.). The Court also stated that, since "a false tipster would think twice before using" an emergency 911 system that allows the authorities to obtain the tipster's telephone number and to record the call for future voice identification, the instant tipster's decision to make her report via the 911 system further reflected her veracity (572 US at ___, 134 S Ct at 1689-1690). In addition to finding the tip reliable, the Court concluded that the caller's report had provided the officers with reasonable suspicion that the driver of the truck had engaged in criminal, as opposed to innocuous, activity because the report noted that the driver had run the caller off the road in a telltale sign of unlawful drunk driving (see at 572 US at ___, 134 S Ct at 1690-1692).

The dissenting Justices concluded that the anonymous tip was not sufficiently corroborated to establish reasonable suspicion (see 572 US at ___, 134 S Ct at 1692-1694 [Scalia, J., dissenting]). Noting that in White the Court had found an anonymous tip to be reliable based on the predictive information reported by the tipster, the dissent pointed out that no similar predictive information bolstered the tip accusing the Navarettes (see 572 US at ___, 134 S Ct at 1693). The dissent stated, "The claim to `eyewitness knowledge' of being run off the road supports not at all its veracity; nor does the amazing, mystifying prediction (so far short of what existed in White) that the petitioners' truck would be heading south on Highway 1" (id.).

Otherwise, the dissent concluded that little, if anything, demonstrated the reliability of the 911 caller's report, and the dissent took issue with the majority's reliance on the caller's use of the 911 system, saying:

In light of the majority and dissenting opinions in Navarette, it is clear that, under the Federal Constitution, predictive information is not an essential indicium of reliability necessary to support a vehicular stop based on an anonymous tip, for the tip in Navarette included no such information. Rather, other factors, such as a tipster's statement indicating that he or she personally observed someone engaged in suspicious behavior, may supply the requisite indicia of reliability that allow the tip to serve as the basis for a stop (see Navarette, 572 US at ___, 134 S Ct at 1688-1689). Accordingly, our passing comment in Moore that "[a]n anonymous tip cannot provide reasonable suspicion to justify a seizure, except where that tip contains predictive information" (Moore, 6 NY3d at 499) is no longer an accurate statement of federal constitutional law (cf. majority mem at 1141). However, there remains a question as to whether it should become the law of New York under the State Constitution.

B

In the wake of Navarette, the parties in the instant cases propose various state constitutional tests for determining whether an anonymous hearsay account of criminal activity is sufficiently reliable to authorize a brief investigatory stop of a person or his or her automobile. Defendants in all three cases urge us to hold that the State Constitution forbids a police officer to detain a suspect based on an anonymous tip unless the tip contains predictive information. In Argyris and DiSalvo, the People press for adoption of Navarette's totality-of-the-circumstances analysis as the law of New York. Regardless of the proper baseline for the reliability of a tip supporting a stop, the People contend that we should not prevent the police from stopping a suspect based on a tip that complies with the Aguilar-Spinelli rule. In Johnson, the People ask us to overrule our prior decisions adopting the Aguilar-Spinelli test for the reliability of a tip in the probable cause context. Instead of the Aguilar-Spinelli standard, the People maintain, our state constitutional jurisprudence should employ the analyses in Gates and Navarette to determine whether an anonymous tip can create probable cause or reasonable suspicion.

I would not adopt wholesale the standards advocated by the parties under the State Constitution. Instead, for the reasons that follow, I would hold that, under the State Constitution, the police may not rely on an anonymous tip to briefly detain or arrest a suspect unless the tip satisfies both prongs of the Aguilar-Spinelli test.

In our existing search and seizure jurisprudence under the State Constitution, we have not set forth any clearly defined minimum standard of reliability in an anonymous tip that permits a police officer to conduct a De Bour-level-three stop. Nonetheless, our long-standing practice of granting New York citizens enhanced protection against unwarranted police intrusions based on hearsay, which originally prompted us to incorporate the Aguilar-Spinelli rule into probable cause determinations, supports the extension of the Aguilar-Spinelli rule to the evaluation of a level-three stop.

In that regard, although the Federal and State Constitutions' search and seizure provisions first arose from a shared fear that the sovereign might oppress the governed by arresting them upon "common rumor and report rather than upon proof of reasonable grounds for believing a crime to have been committed" (Elwell, 50 NY2d at 236), this concern has taken on special significance under the State Constitution (see People v Griminger, 71 N.Y.2d 635, 638-641 [1988]; Johnson, 66 NY2d at 406-407; Elwell, 50 NY2d at 241). For that reason, we have rejected Gates and adhered to the Aguilar-Spinelli standard for evaluating the reliability of a tip as the basis for an arrest (see People v Griminger, 71 N.Y.2d 635, 638-641 [1988]; Johnson, 66 NY2d at 406-407; Elwell, 50 NY2d at 241). And, the same concern that caused us to follow the Aguilar-Spinelli rule in the arrest context is still valid today and applies with equal force to investigatory stops precipitated by anonymous tips. As is true of an arrest premised on uncorroborated anonymous hearsay, a stop based on an unreliable tip may unjustly expose an individual to a high degree of physical intrusion without any credible cause for suspicion. If such stops were permitted, the police could freely abuse the people on authority of the most preposterous reports, and malicious tipsters could easily use incredible rumors to convince the police to physically harass the targets of the tipsters' ire. As in the arrest context, the State Constitution must reduce these dangers by precluding the police from physically seizing an individual based on a tip that does not meet Aguilar-Spinelli's reliability criteria.

In addition, the application of the Aguilar-Spinelli test to anonymous hearsay reports underlying investigatory stops furthers "the aims of predictability and precision in judicial review of search and seizure cases" (Johnson, 66 NY2d at 407). Because we have used the Aguilar-Spinelli test to judge the reliability of hearsay tips for the past 39 years (see People v Hanlon, 36 N.Y.2d 549, 556 [1975]), defendants have relied on that standard as a basic guarantee of their rights, anchoring their expectations regarding the legality of a seizure and the admissibility of evidence obtained therefrom in the Aguilar-Spinelli framework. Likewise, New York law enforcement officers have become accustomed to the need to conform their practices to the dictates of the Aguilar-Spinelli rule, and there is no evidence or logical basis on which to conclude that the law enforcement community has found the demands of the rule to be incomprehensible or unusually burdensome. Given that our state's jurists have also applied the Aguilar-Spinelli doctrine routinely and without apparent difficulty in the arrest context, they should be able to reliably and fairly employ that standard when deciding whether a tip is reliable enough to support a stop, thereby enhancing the predictability of judicial review.

Although defendants find the Aguilar-Spinelli test too lax and the People characterize it as too strict, both criticisms principally derive from a shared belief that the test's two prongs do not independently add much of value to the reliability determination and ignore other relevant indicia of reliability or flaws in a given tip. My concurring colleague shares this concern (see concurring op of Smith, J. at 1142). But our precedent readily answers those charges. As we explained in People v Rodriguez (52 N.Y.2d 483 [1981]) and People v DiFalco (80 N.Y.2d 693 [1993]), each prong of the Aguilar-Spinelli test acts as a vital independent safeguard against unwarranted governmental intrusions based on unreliable hearsay. The basis-of-knowledge prong guarantees that the police do not forcibly detain a citizen pursuant to the report of an informant who is honest but has relied on incomplete secondhand knowledge of the relevant events (see DiFalco, 80 NY2d at 698; Rodriguez, 52 NY2d at 491). The veracity prong separately ensures that the police will not stop someone simply because an unscrupulous informant, who possesses plenty of accurate personal knowledge of what happened, twists the facts to falsely accuse the suspect of a crime (see DiFalco, 80 NY2d at 698-699; Rodriguez, 52 NY2d at 488-490). The twofold framework accounts for the reality that a tipster's surfeit of honesty cannot fully compensate for a deficit in his knowledge (and vice versa), regardless of what other types of information in the tip might be deemed indicia of reliability under Navarette. Thus, the Aguilar-Spinelli test's separate prongs establish adequate protections against seizures based on unreliable hearsay tips while simultaneously providing a practical and analytically useful lens through which to view the trustworthiness of such tips.

The People ask us to abandon the Aguilar-Spinelli test on the theory that its inflexibility has made it intolerably difficult for the police to comply with. The People claim that, because every state in the Union, save for New York and five others, has rejected the Aguilar-Spinelli standard and adopted the Gates analysis, those other jurisdictions' experiences with the Aguilar-Spinelli rule must have proven that the rule is unworkable and wholly incompatible with effective law enforcement. However, while the considered opinions of other jurisdictions often carry significant weight in our evaluation of legal doctrine, I do not find the out-of-state authority cited by the People to be a sufficiently compelling basis on which to cast aside the Aguilar-Spinelli rule. Those out-of-state decisions do not compensate for the absence of proof that the Aguilar-Spinelli rule has intolerably taxed the New York law enforcement community over the decades in which we have applied the rule. And, although it is generally desirable to maintain uniformity with the law of other jurisdictions when doing so does not compromise a significant public policy or legal principle unique to New York, we have already held that considerations of uniformity in the evaluation of anonymous tips must yield to "aims of predictability and precision in judicial review of search and seizure cases and the protection of the individual rights of our citizens," which are "best promoted by applying [the] State constitutional standards" embodied in the Aguilar-Spinelli standard (Johnson, 66 NY2d at 407).

For their part, defendants and my dissenting colleagues (see dissenting op of Rivera, J. at 1169, 1176-1177) interpret Moore as creating a state constitutional rule that, even where a tip meets the Aguilar-Spinelli standard, it cannot support the temporary detention of a suspect if it does not also contain predictions of the suspect's future activities. However, for reasons I have already explained, Moore does not establish such a state constitutional rule. Nor do I now perceive any reason to create a special predictive information requirement under the State Constitution because the Aguilar-Spinelli standard fully accounts for the value of the type of predictive information discussed in White and J.L. As the Supreme Court noted in White, an anonymous tip containing predictive information is highly reliable precisely because it shows "not only that the [tipster] [i]s honest," i.e., that his or her veracity is established, "but also that [the tipster] [i]s well informed," meaning he or she has a reliable basis of knowledge of the suspect's crime (White, 496 US at 332). In other words, a tip's prediction of the suspect's future activities is simply one of many possible pieces of information that can satisfy the basis-of-knowledge prong of the Aguilar-Spinelli test. Therefore, the presence or absence of predictive information in a tip already carries its proper significance in the Aguilar-Spinelli framework and need not be transformed into an independent prerequisite for a finding of reliability.

According to defendants, a predictive information requirement for the reliability of an anonymous tip is necessary to ensure that the police can "test" the credibility of the tip via their own observations of the behavior predicted by the tipster. However, when compared to other forms of information that satisfy the basis-of-knowledge prong of the Aguilar-Spinelli test, predictive information does not necessarily make the police more or less capable of "testing" the truthfulness of a tipster's account of the crime itself at the constitutionally critical juncture; even when armed with predictive information, the police still must usually decide whether to seize a suspect before they can personally observe that the suspect has committed or will commit a crime as described by the tipster.

White illustrates this point. There, the tipster gave the police exact predictions of the suspect's future movements and made an allegation that the suspect would be carrying a case full of drugs, but before detaining the suspect, the police did not personally observe her holding the case and were unable to test the truthfulness of the tipster's report that she possessed drugs (see White, 496 US at 327). It was only after the police stopped the suspect and searched her car that they were able to confirm that the tipster had accurately reported the suspect's possession of the drugs (see id.). Hence, prior to the stop, the predictive information in the tip did not assist the police in "testing" whether the tipster had truthfully reported the suspect's illegal acts. Thus, the facts of White reflect the general truth that, regardless of whether an anonymous informant evidently knows about an individual's crime via personal affiliation or firsthand observation, the police usually cannot corroborate the informant's allegations of criminal conduct until they stop the suspect, and predictive information rarely resolves that difficulty.

In addition, a predictive information requirement would do little to eliminate the concern that a tipster will maliciously send false information to the police. In that regard, only people with unique knowledge of a suspect's affairs, such as a close friend, relative, accomplice or insider in the suspect's criminal scheme, can provide the police with predictive information, and consequently a predictive information requirement would force the police to rely exclusively on such insiders. Yet, contrary to defendants' apparent supposition, insider tipsters are no less likely than members of the general public to concoct baseless accusations of criminality as a way to harass a suspect. Indeed, one can conceive of many examples of a tipster who is familiar with a suspect's plans and might forward them to the police, along with a fabricated report of criminal activity, to settle a score.

Defendants' proposal to categorically forbid the police to conduct an investigatory stop predicated upon a tip that lacks predictive information would also place an excessive restraint on law enforcement. Because members of "[t]he general public" who witness a crime "ha[ve] no way of knowing" what the perpetrator will do next (see White, 496 US at 332), they cannot supply any predictive information to the police, and therefore a predictive information requirement would prevent the police from seizing a suspect solely in reliance on a tip received from an ordinary citizen who wishes to report a crime while remaining anonymous. Given that many crimes are reported to the police exclusively in that way, defendants' rule would unacceptably curtail the punishment and prevention of numerous serious offenses that are credibly reported by regular citizens. Like the Court (see majority mem at 1141), I cannot endorse this approach that senselessly endangers the public and erodes enforcement of the law without any compelling justification. I agree with my dissenting colleagues that the State Constitution must provide robust protections for the rights of defendants, but the strong safeguards of article I, § 12 of the State Constitution do not extend so far as to completely overthrow the sensitive balance between individual liberty and public order contemplated by the Constitution.

In light of the considerations outlined above, I would conclude that the Aguilar-Spinelli test should govern the determination of whether an anonymous tip is sufficiently reliable to authorize the physical detention of a person by the police.

Of course, a court's finding that an anonymous tip is reliable under the Aguilar-Spinelli test does not end the inquiry into the lawfulness of a stop or arrest based on that tip. After all, "[e]ven a reliable tip will justify an investigative stop only if it creates reasonable suspicion that criminal activity may be afoot" (Navarette, 572 US at ___, 134 S Ct at 1690 [internal quotation marks and citation omitted]). Thus, as a matter of law and logic, an officer receiving an anonymous tip cannot stop the suspect unless the tipster's description of the suspect's criminal conduct includes such details as would create reasonable suspicion in an officer who had seen the same details or learned such facts from a fellow officer (see generally People v Hendricks, 25 N.Y.2d 129, 136 [1969]). Likewise, where the tipster's statements about the actual crime feature the sort of details that would engender probable cause when gleaned by an officer via personal observation or another reliable source, the officer receiving the tip may lawfully arrest the suspect. Moreover, it is well settled that, even if a tip does not meet the Aguilar-Spinelli standard or does not feature adequate details to confer reasonable suspicion upon the officer who hears it, the officer's personal observation of the suspect engaged in suspicious activity may, in combination with the tip, give rise to reasonable suspicion or probable cause (see Elwell, 50 NY2d at 241 [concluding that, where an informant "d(oes) not indicate the basis for his knowledge," "the rule under our Constitution should be that a warrantless search or arrest will be sustained only when the police observe conduct suggestive of, or directly involving, the criminal activity"]).

III

Having laid out relevant state constitutional guidelines, I now address the application of those rules to the facts of the cases before us.

A

In Argyris and DiSalvo, I conclude that the police lawfully stopped defendants' car based on an anonymous tip that was reliable under the Aguilar-Spinelli test and sufficiently detailed in its description of their criminal conduct to create reasonable suspicion. On the reliability front, the 911 caller who accused defendants Argyris and DiSalvo of having a gun in their car plainly supplied the police with information that satisfied the veracity prong of the Aguilar-Spinelli test. Since the "veracity prong of the Aguilar/Spinelli test may, in a proper case, be established through corroboration where the police have verified only noncriminal details of activity referred to in the informant's statement" (DiFalco, 80 NY2d at 699), the 911 caller's statements about numerous aspects of the suspects' appearance, vehicles and non-criminal activity, all of which were corroborated by the officers' observations of the same, fulfilled the veracity requirement.2

Turning to the basis-of-knowledge prong, that prong can be established, as it was here, by an anonymous informant's statement that he or she has just personally witnessed an unconcealed crime. Given that the report is allegedly contemporaneous, the police can verify some aspect of the informant's reliability by confirming that the individual accused of criminality remains in the area reported by the tipster shortly after the tip has been received. By claiming personal knowledge, the tipster puts his or her own credibility on the line rather than seeking to hide behind a secondhand hearsay source; the tipster knows that, if the police arrive on the scene and see that the situation is not as described, they will discredit the tip completely rather than assume that the error resulted from the miscommunication of only a few details by another individual who transmitted the information to the tipster. Furthermore, from the claim of eyewitness information and the other contents of the tip, the police may discern whether it is plausible for someone to have personally seen the activities alleged under the circumstances in which they have purportedly occurred.

For those reasons, contrary to the contention of my dissenting colleagues (see dissenting op of Rivera, J. at 1177-1179, 1179-1180), the tipster's roughly contemporaneous assertion of an unconcealed criminal act may satisfy the basis-of-knowledge prong of the Aguilar-Spinelli test in this context (see Spinelli, 393 US at 425 [White, J., concurring] ["(W)hat is necessary under Aguilar is one of two things: the informant must declare either (1) that he has himself seen or perceived the fact or facts asserted; or (2) that his information is hearsay, but there is good reason for believing it"]; Brown v United States, 365 F.2d 976, 979 [DC Cir 1966] [where police received a report of a robbery of a certain establishment from an anonymous victim, who allegedly personally witnessed the robbery, the basis-of-knowledge prong was satisfied]; People v Torres, 155 A.D.2d 231, 232 [1st Dept 1989] ["As to the second prong of the Aguilar-Spinelli test, the informant's basis of knowledge, that was easily established in that the informant stated that he was basing his report on his own personal knowledge, gained through direct observations"]; Commonwealth v Amral, 407 Mass. 511, 514, 554 N.E.2d 1189, 1192 [1990] ["The informant's observation of the contraband in the place to be searched satisfies the basis of knowledge test"]; cf. United States ex rel. Kislin v State of New Jersey, 429 F.2d 950, 953-954 [3d Cir 1970] [indicating that affidavit stating an unidentified informant, who was not identified as a confidential informant with prior dealings with the police, had "personal knowledge" that defendants had been engaged in specified illegal gambling activities satisfied the basis-of-knowledge prong but not the reliability prong]).

Since the 911 caller here stated that he had acquired eyewitness knowledge of defendants' illegal weapon possession at around the time of the call, his report met the basis-of-knowledge prong. Indeed, the caller's report was clearly contemporaneous, as he said that he was coming out of a building at his current location when he saw one of the suspects put a gun in the Mustang, and he added that the suspect "just went" down to 28th Street.3 Because the caller's tip satisfied both prongs of the Aguilar-Spinelli test, the police were entitled to effect a seizure in reliance on it, assuming that the tip contained enough information about the crime to create reasonable suspicion.

In that regard, as previously discussed, a tip that is reliable under the Aguilar-Spinelli rule nonetheless cannot authorize a seizure unless it also features a sufficient description of the crime to give rise to reasonable suspicion, in the case of a Terry stop, or probable cause, in the case of an arrest. Here, in addition to being reliable, the tip contained enough information about the crime to create reasonable suspicion. Although a more fleshed-out report of criminal activity would have been preferable, the tipster's basic statements were sufficient in light of the nature of the crime alleged. In that respect, it should be noted that the crime at issue, illegal gun possession, naturally tends to be described in sparse fashion because it does not involve many detailed movements, and one can accurately sum up someone's illegal gun possession by saying the person is holding a gun in a public place. Even so, the caller here provided more than the typical simplistic statement that someone "has" or "is holding" a gun. The caller explained that: (1) one of the large white males possessed a gun; (2) the gun was a "big gun"; and (3) the gun was specifically placed in the back of the car. While not overwhelmingly detailed, these allegations sufficed to supply the police with reasonable suspicion that defendants and the other occupants of the car were involved in unlawful gun possession outside their homes or places of business (see Penal Law §§ 265.01 [1]; 265.03 [1], [3]). Therefore, on this record, the courts below did not err in finding that the police lawfully stopped the car based on reasonable suspicion of illegal weapon possession, in compliance with the State Constitution.

When the police surrounded the car with officers, drew their weapons and ordered defendants out of the car, they acted reasonable and lawfully out of a justifiable concern for their safety (see People v Brnja, 50 N.Y.2d 366, 372 [1980]; see also Terry, 392 US at 27; United States v Jackson, 652 F.2d 244, 249 [2d Cir 1981], cert denied 454 U.S. 1057 [1981]; see generally People v Coutin, 78 N.Y.2d 930 [1991]). Once defendant DiSalvo emerged from the car with a gun visible on his waistband, Officer Valles had probable cause to arrest him. Likewise, when defendant Argyris exited the car wearing a bulletproof vest, Valles had probable cause to believe that Argyris was also involved in armed activity, as is often true of those who wear bulletproof vests. Because Valles's observations further corroborated the 911 caller's allegations that the men had guns in their car, Valles had the right to search the passenger compartment of the car for additional signs of the gun possession mentioned by the caller (see Arizona v Gant, 556 U.S. 332, 335 [2009]). Upon doing so, Valles lawfully recovered ammunition in the backseat, corroborating the caller's claim that he had seen defendants or their companions place a gun in the back of the car. Since the record does not support a finding that the police violated defendants' federal or state constitutional rights, I agree with the Court that the lower courts properly denied their suppression motions (see majority mem at 1140-1141).4

B

In People v Johnson, I conclude that the police unlawfully stopped defendant's car based on an anonymous 911 call that did not set forth the basis of the caller's knowledge of defendant's alleged crime, as required under the second prong of the Aguilar-Spinelli test. The caller did not claim to have personally witnessed defendant illegally driving while intoxicated, and the caller neither made any prediction of defendant's future behavior which might have suggested that he or she had insider knowledge of defendant's affairs nor stated that he or she had learned of defendant's acts from another credible source. In the absence of any such indicia of the basis of his knowledge, Cunningham improperly relied on the 911 call as a basis for stopping defendant's car on suspicion of driving while intoxicated (see Spinelli, 393 US at 425 [White, J., concurring]; see also William II, 98 NY2d at 99). Moreover, the caller's statements could not have caused Cunningham to reasonably suspect that defendant was committing a crime. The caller made a conclusory and equivocal assertion that defendant was "sick or intoxicated," and he or she did not describe any particular action on defendant's part that could have reasonably caused the police to accept her conclusion. Thus, the police could not have suspected defendant of anything more than "an isolated episode of past recklessness" (Navarette, 572 US at ___, 134 S Ct at 1690).5

In addition, while Deputy Cunningham saw defendant commit a traffic violation, he lacked authority to pull defendant's car over on this basis because he was outside his area of geographical jurisdiction and, thus, could stop a vehicle only on reasonable suspicion of conduct rising to the level of a crime. The violation did not confirm the reliability of the 911 call or provide Cunningham with reasonable suspicion of driving while intoxicated because, in context, defendant's behavior appeared to be, at most, a brief sign of negligent driving consistent with a minor traffic infraction. When defendant made an illegal wide turn onto the street to his right, he entered the lane meant for oncoming traffic for a mere moment, quickly correcting himself in a way that belied suspicion of intoxicated driving.6 Furthermore, defendant's behavior prior to the stop also gave the Deputy no cause to question his sobriety. When Cunningham first saw defendant, he was properly stopped at a stop sign, and defendant then evidently made a lawful and steady turn onto Route 21. Thus, the entirety of the record does not support the lower courts' finding that Cunningham reasonably suspected defendant of driving while intoxicated, and the courts below erred in concluding that Cunningham lawfully stopped defendant's car and questioned him. And, because Deputy Drake's actions were precipitated by the unlawful stop, the breath test results obtained by Drake should have been suppressed.7

IV

In People v Argyris and People v DiSalvo, I find that the lower courts did not err in denying defendants' suppression motion. In People v Johnson, I believe the lower courts erred in failing to grant defendant's suppression motion. Accordingly, in People v Argyris and People v DiSalvo, I vote to affirm the respective orders of the Appellate Division. In People v Johnson, I vote to reverse County Court's order, grant the suppression motion and dismiss the accusatory instrument.

READ, J. (dissenting in People v Argyris and People v DiSalvo, concurring in result in People v Johnson).

We have held that an anonymous tip supplies reasonable suspicion only if it "contains predictive information — such as information suggestive of criminal behavior — so that the police can test the reliability of the tip" (People v Moore, 6 N.Y.3d 496, 499 [2006]; see generally dissenting op of Rivera, J. at 1176-1179 [discussing Moore]). In light of the United States Supreme Court's recent decision in Navarette v California (572 US ___, 134 S.Ct. 1683 [2014]), the People urge us to dispense with the requirement for predictive information and adopt a totality-of-the-circumstances or some other more expansive test to justify a forcible stop based on an anonymous tip. These appeals therefore pose the question whether the police can have reasonable suspicion to stop an individual based solely on an anonymous tip that does not provide predictive information. I would adhere to our Moore precedent and answer "No."

Where to draw the line separating permissible from forbidden police conduct inevitably requires courts to balance the interests of individual privacy and liberty on the one hand and public safety and security on the other. This is usually not an easy exercise with obvious answers. That is certainly the case here, where Judge Smith's and Judge Abdus-Salaam's concurrences and Judge Rivera's dissent all make excellent arguments in support of the different standards that they espouse. And Navarette itself was a vigorously disputed 5-4 decision. I recognize, of course, that we might have decided Moore differently if, at the time, federal constitutional law had allowed us to do that. Still, the Moore rule is clear, reasonable and well-established. I therefore see no reason to depart from it.

RIVERA, J. (dissenting in People v Argyris and People v DiSalvo, concurring in People v Johnson).

In these cases we must decide whether police have reasonable suspicion to justify a forcible stop based solely on an anonymous informant's uncorroborated "tip" that lacks any information by which to test the reliability of the informant or the information supplied. Information from informants, in particular anonymous informants who intentionally keep their identity secret and with whom law enforcement personnel have no known prior experience, is inherently suspect. The value of an informant's tip has always depended on the credibility of the informant and the basis of the tip information. Where, as here, an anonymous informant makes unsubstantiated assertions about illegal activity, providing only generally observable descriptive information about the individual subject of the tip, but lacking predictive information of the subject's criminal conduct, the tip alone cannot provide reasonable suspicion for police to effect a forcible stop.

Anonymous tips, nonetheless, may advance law enforcement purposes by providing information leading to an independent police investigation. In cases where an anonymous tip is confirmed by police work and personal observation, the tip, as corroborated, may supply reasonable suspicion, which is "the quantum of knowledge sufficient to induce an ordinarily prudent and cautious [person] under the circumstances to believe criminal activity is at hand" (People v Cantor, 36 N.Y.2d 106, 112-113 [1975]).

In People v Moore, we held that in order to justify a forcible stop, an anonymous tip must "contain[] predictive information — such as information suggestive of criminal behavior — so that the police can test the reliability of the tip" (6 N.Y.3d 496, 499 [2006]). Four members of the Court now reject Moore's precedential standing. In turn, a bare majority, unable to choose between a totality of the circumstances analysis and a diluted version of the Aguilar-Spinelli test, concludes in a memorandum opinion that under either standard the tip in Argyris and DiSalvo supports a finding of reasonable suspicion, but the tip in Johnson is unreliable. In separate concurring opinions, two members of the majority provide rationales in support of their legal standard of choice.

It appears that my colleagues accept as a legal precept the sufficiency of an informant's untested and unsubstantiated allegation of personal knowledge of criminal activity as a basis for a tip's reliability. By doing so, my colleagues bolster the constitutional significance of an uncorroborated anonymous tip that provides nothing more than a self-referential statement that the informant saw some individual commit a crime. Such an approach places every member of our society at risk of police intrusions based on the flimsiest of bases, and is contrary to our prior holding in Moore. I dissent.

I.

The appeals before us involve information from anonymous tipsters, persons not known to law enforcement and who seek to conceal their identity. Anonymous tipsters differ from known police informants, whose identities are not secret, and with whom police may have prior experience as reliable sources of information about criminal activity. In either case, informants, unlike police officers, "are not regarded as presumptively reliable or honest" (Illinois v Gates, 462 U.S. 213, 277 [1983, Brennan, J., dissenting]). The case law illustrates a general concern about the use of information from informants, in particular anonymous tipsters, as a basis for police intrusions because of the ease with which anonymity facilitates false reporting (see e.g. People v Rainey, 228 A.D.2d 285, 287 [1st Dept 1996] ["The lack of accountability for false reports in such instances renders anonymous tips the weakest sort of information" (citation omitted)]). In contrast, a known informant's "reputation can be assessed and [the informant] can be held responsible if [the] allegations turn out to be fabricated" (Florida v J.L., 529 U.S. 266, 270 [2000], citing Adams v Williams, 407 U.S. 143, 146-147 [1972]).

In order to provide a basis for probable cause to arrest, or reasonable suspicion to stop and detain the subject of a tip, courts have applied tests by which to measure the tip's reliability. The necessary indicium of reliability demanded in these cases focus on the informant's credibility and the basis of the tip information.

The Aguilar-Spinelli test, drawn from the United States Supreme Court's decisions in Aguilar v Texas (378 U.S. 108 [1964]) and Spinelli v United States (393 U.S. 410 [1969]), as applied to probable cause determinations based on information from known informants, requires that the informant is reliable and that there is a basis for the knowledge of the informant's tip (Spinelli, 393 US at 413, 416). To avoid unreasonable police intrusions, the informant's basis of knowledge must be supported by details substantial enough to demonstrate that the informant is not merely relying on rumor (id.).

In both Aguilar and Spinelli, the Court found the informants' tips constitutionally insufficient. In Aguilar, the affidavit stated only that the police were informed by an unnamed "credible person" that defendant's home contained illegal drugs (378 US at 109). In Spinelli, the affidavit stated more, including that defendant was observed by investigators traveling repeatedly to a particular apartment that contained two telephone lines, that defendant was known to the affiant and other law enforcement agents as a bookmaker, and that an unidentified informant had stated that defendant was using the two telephones in a bookmaking operation (393 US at 413-414). Nevertheless, each failed to satisfy the threshold requirements.

In Gates, the Supreme Court abandoned the Aguilar-Spinelli test, demoting its two requirements to mere considerations in a broad "totality-of-the-circumstances" analysis (462 US at 238). There, the Court considered the reliability of an anonymous letter sent to police by mail. The letter contained specific information detailing the "future actions of third parties ordinarily not easily predicted" (id. at 245). The Court found that the anonymous letter alone was insufficient under Aguilar-Spinelli. However, police "corroboration of major portions of the letter's predictions" provided "fair probability that the writer of the anonymous letter had obtained his entire story either from [defendants] or someone they trusted," therefore making it apparent that the judge had a "substantial basis for ... conclud[ing] that probable cause to search [defendants'] home and car existed" (id. at 246 [internal quotation marks omitted]).

The Court applied the totality of circumstances analysis in Alabama v White, where it held that in order for an anonymous tip to provide reasonable suspicion to justify a vehicle stop, the tip needed some "indicia of reliability" (496 U.S. 325, 327 [1990]). There, police received an anonymous call indicating:

In Adams v Williams, the informant was known to the police officer when he approached the officer and advised him "that an individual seated in a nearby vehicle was carrying narcotics and had a gun at his waist" (407 US at 145). The Court noted that the information provided was immediately verifiable and, if false, subjected the informant to immediate arrest thus making this "a stronger case than obtains in the case of an anonymous telephone tip" (id. at 146). The Court stressed, however, that "[o]ne simple rule will not cover every situation" and "[s]ome tips, completely lacking in indicia of reliability, would either warrant no police response or require further investigation before a forcible stop of a suspect would be authorized" (id. at 147).

In Florida v J.L. (529 U.S. 266 [2000]), the Supreme Court clarified that to justify a forcible stop, reasonable suspicion based on an anonymous tip required predictive information of future criminal behavior. There, police officers stopped and frisked the defendant after receiving an anonymous tip that a young Black male was standing at a particular bus stop, wearing a plaid shirt and carrying a gun. Other than the fact that the defendant matched the general description provided by the informant, the officers had no reason to suspect him or his companions of illegal activity. Finding the informant's descriptive information of defendant insufficient to satisfy the constitutional requirement for a stop and frisk, the Court stated that an anonymous tipster's reliability would be demonstrated only if the suspect subsequently engaged in actions suggestive of concealed criminal activity, which the anonymous tip predicted in detail (id. at 271-272). That is "reasonable suspicion ... requires that a tip be reliable in its assertion of illegality, not just in its tendency to identify a determinate person" (id. at 272).

The Supreme Court revisited the issue of the reliability of anonymous informants in the context of a drunk driving case. In Navarette v California (572 US ___, 134 S.Ct. 1683 [2014]), a divided Court applied the totality of the circumstances test, and concluded that while police failed to observe any criminal conduct, they had reasonable suspicion to stop the defendants based on a 911 caller's description of defendants' pickup truck which the caller alleged had minutes before run her off the road.1 According to the majority, the call had sufficient indicia of reliability because the informant had been an eyewitness to the event, whereas in J.L., "the tip provided no basis for concluding that the tipster had actually seen the gun" (572 US at ___, 134 S Ct at 1689). Further, the Court credited the informant with having used the 911 system, which permits tracking of calls, and which allows for prosecution of those who make false reports. Last, the Court noted that the caller reported the type of dangerous conduct that resembles drunk driving, suggesting the informant's conclusion was correct.

Our Court has also been suspicious of informants, especially anonymous tipsters, and thus demands that the informant's reliability be established in order to justify probable cause or reasonable suspicion. Early on we "characterized the use of anonymous information to justify intrusive police action as `highly dangerous'" (People v De Bour, 40 N.Y.2d 210, 225 [1976], citing People v Taggart, 20 N.Y.2d 335, 343 [1967]). Fearing the potential risks associated with false anonymous tips, we observed that

In People v La Pene (40 N.Y.2d 210 [1976]), the companion case to De Bour, we concluded that an anonymous telephone tip, in the proper case, could provide police with reasonable suspicion to stop and frisk the subject of the tip. However, we held that the tip in La Pene, alleging only that there was a Black male inside a bar, wearing a red shirt with a gun (id. at 221), was vague and thus insufficient. We noted that it was "significant though not determinative ... that [the tip] was garnered from an anonymous source" (id. at 224).

Even where the informant had provided reliable information in the past, we have declined to uphold a search where the police were only able to corroborate defendant's identification, but not any details suggestive of criminal activity (People v Elwell, 50 N.Y.2d 231, 237 [1980] ["personal police observation corroborative of data received from the informant should be regarded as sufficient only when the police observe facts suggestive of criminal activity" (emphasis added)]). We reasoned that "[o]therwise privacy and liberty may be invaded by a warrantless search or arrest based solely on the quality of the informant and not at all on the quality of the information, i.e., its suggestiveness of criminal activity" (id.). Thus, "[b]earing in mind the balance to be struck between the individual's constitutional right to be free of official interference by way of search or arrest with society's interest in preventing crime and apprehending criminals" (id. at 241), we concluded that

After the Supreme Court's decision in Gates, we rejected the totality of the circumstances test and, as a state constitutional matter, continued to apply the Aguilar-Spinelli test to probable cause determinations involving informants. Thus, in People v Johnson, we stated that "the protection of the individual rights of our citizens [was] best promoted by applying State constitutional standards" (66 N.Y.2d 398, 407 [1985]). Soon thereafter, in People v Griminger (71 N.Y.2d 635 [1988]), we again adhered to Aguilar-Spinelli, observing that requiring adherence to the test would "prevent the disturbance of the rights of privacy and liberty upon the word of an unreliable hearsay informant, a danger we perceive under the Gates totality-of-the-circumstances test" (id. at 641).

Distinguishing between the two Aguilar-Spinelli requirements, we restated in People v DiFalco (80 N.Y.2d 693 [1993]) that the informant's basis of knowledge could be corroborated by sufficient details "suggestive of or directly related to criminal activities" (id. at 697, citing Elwell, 50 NY2d at 236). We then held that the informant's reliability may be established by corroboration based on "independently verified details, although not of themselves criminal in nature" (id. at 699). We stressed, however, that those details "may not be merely peripheral to the reported criminal scheme; they must fit within the informant's story of the contemplated crime as activities which are significant and essential to carrying it out" (id.). Thus, we confirmed that information suggestive of criminal activity was central to the Aguilar-Spinelli requirements, finding "[t]he separate basis of knowledge and veracity requirements of Aguilar/Spinelli are analytically independent and each must be satisfied" (id. at 697; see also Johnson, 66 NY2d at 402-403; United States v Harris, 403 U.S. 573, 592 [1971, Harlan, J., dissenting]).

In three cases particularly relevant to the instant appeals, we imposed explicitly the predictive information requirement of J.L. to street encounters and vehicle stops. In People v William II (98 N.Y.2d 93 [2002]), the police received an anonymous call indicating a man named "Will" had just been involved in a drive-by shooting. The anonymous informant provided a description of "Will," as well as his location, and cautioned that he was armed. When police arrived they found defendant in a group, with another man resembling the description given by the caller; however from the manner in which defendant was dressed, the police immediately knew he was not carrying a concealed weapon. Nevertheless, the police frisked defendant and the other man. We held that "[t]he tip not only lacked predictive information that would permit the police to test the caller's knowledge, but was also rendered suspect when directly contradicted by the police officer's observation[s]" (id. at 99). Accordingly, we suppressed marijuana recovered from the defendant.

In People v Rodriguez, the companion case to William II, an anonymous caller described a light-skinned Hispanic male, in his twenties, with black hair, wearing a black-and-white checkered shirt and jeans and allegedly carrying a gun. Two hours later the police saw the defendant, who fit the description, entering the back of a livery cab. Police stopped the cab and as they approached, defendant allegedly dropped a handgun out of the window. We held that the anonymous tip lacked predictive information, stating "the only basis for reasonable suspicion advanced before the suppression court for stopping the vehicle in which defendant was a passenger was that he matched the physical description provided by an anonymous tipster. Without more, the tip could not provide reasonable suspicion to stop the car" (id.).

In People v Moore (6 N.Y.3d 496 [2006]), an anonymous caller informed police that there was a dispute involving a Black male with a gun, approximately 18 years old and wearing a gray jacket and red hat. When the police arrived they saw defendant, who matched the description. As they approached, defendant started to walk away. The police caught up with defendant and, with guns drawn, subjected him to a frisk. We held that "[a]n anonymous tip cannot provide reasonable suspicion to justify a seizure, except where that tip contains predictive information — such as information suggestive of criminal behavior — so that the police can test the reliability of the tip" (id. at 499, citing J.L., 529 U.S. 266).

In assessing the propriety of a forcible stop under our De Bour framework, we discussed the liberty interest at risk from investigatory stops based on anonymous tips. We observed,

II.

Central to these cases are the requirements of reliability of the anonymous informant and the credible basis for the tipster's information. Testing the reliability of the informant addresses whether the informant is truthful, and not motivated to fabricate. Confirming the tipster's information reflects a principal concern that the information about criminal activity be based on facts and data which make it likely to be accurate.

Whether under the Aguilar-Spinelli test for probable cause, or the less demanding reasonable suspicion standard, the courts seek to ensure a tip is reliable in order to avoid police intrusions based on suspicion and rumor, or fabricated report of illegality. Unlike a known informant, an anonymous informant has no history with law enforcement, and no track record of having provided reliable information in the past. Deprived of the informant's identity, the police have no basis upon which to conclude that the tipster may be trusted. As the courts have recognized, such tips carry the real possibility that individuals will be subjected to police intrusions on the basis of false information by someone who may escape prosecution. Thus, there is every reason to carefully scrutinize the anonymous informant and the tipster's information, and to require corroboration that provides a basis for an officer's supported belief of criminal conduct, taking into account that the source of the information is unknown and untested. Whether the inquiry is to confirm the existence of probable cause for a search or an arrest, or the reasonable suspicion to stop and detain, the tip must have an indicium of reliability.

Reliability may be provided by any number of factors external to the informant (see White, 496 US at 332 [police observation of predictive details evincing the criminal behavior the tip predicted]; People v Cobb, 208 A.D.2d 453 [1st Dept 1994] [police observation of illegality]). Reliability may also be provided by the contents of the tip (see e.g. White, 496 US at 328 [substance of the anonymous tip contained sufficient indicia of reliability to justify reasonable suspicion to stop defendant]). However, as relevant to these appeals, we made clear in Moore that in order to provide reasonable suspicion to justify a forcible stop, an anonymous tip must contain predictive information of criminality (6 NY3d at 499). It is just that simple and just that important.

The requirement that an anonymous tip must contain predictive information ensures that police act based on information that provides a basis for believing the informant is truthful and the tip has a basis in facts and circumstances that reveal criminal activity. This requirement properly balances fundamental constitutional rights of liberty and privacy against concerns about public safety and efficient law enforcement. A predictive information requirement benefits the individual and society by protecting cherished freedoms against what Justice Douglas described as the "powerful hydraulic pressures throughout our history that bear heavily on the [courts] to water down constitutional guarantees" (Terry v Ohio, 392 U.S. 1, 39 [1968]), while also permitting law enforcement to deploy investigative techniques based on experience with informants, with due regard to the practical realities and demands of policing, especially in matters involving fast-paced street encounters.

In an effort to avoid the underlying rationale of our prior approach, the majority claims in Argyris and DiSalvo that the tip's lack of predictive information is not fatal (majority mem at 1141). My concurring colleague, Judge Abdus-Salaam, goes so far as to describe as dicta Moore's legal rule statement that an anonymous tip must contain predictive information before the tip may serve as reasonable suspicion to justify a De Bour level three seizure (see concurring op of Abdus-Salaam, J. at 1153-1154). Indeed, she expounds on this conclusion, arguing that the actual grounds for our decision in Moore were "numerous other aspects of the tip" that showed it was not credible (id. at 1153). This is a revisionist interpretation of Moore and one which distorts this Court's central unambiguous holding that "the tip did not provide any predictive information" (Moore, 6 NY3d at 499). In fact, there are no so-called "numerous" references to credibility problems to be found anywhere in the opinion, only this Court's conclusion that in addition to lacking predictive information, the tip failed to provide accurate descriptive information by failing to correctly portray the unfolding events at the scene.

Judge Abdus-Salaam advocates for the adoption of the two-pronged Aguilar-Spinelli test. If she, in fact, adhered to the actual Aguilar-Spinelli test I might join her opinion, given that before today the Aguilar-Spinelli test imposed a higher standard than what has usually been necessary to establish reasonable suspicion in support of an investigatory stop.

However, the long-standing Aguilar-Spinelli test is not what my concurring colleague promotes. Instead, she embraces a modified version of this test, resting the reasonable suspicion determination "on the quality of the tip's description of the crime itself" (concurring op of Abdus-Salaam, J. at 1144) without the need for predictive information of criminal activity. This is merely "Aguilar-Spinelli lite," excised of the core protective benefits that underlie the original test, and diluting its most salient requirements.

As described, it allows police, on a simple allegation that someone saw somebody do something, to stop anyone, regardless of age or physical condition; at any time, day or night; at any place, whether walking on a public street, sitting in a car, or entering one's home or place of employment. No quotidian moment escapes potential police intrusion. The most basic and innocuous of chores and activities, such as commuting to work or school, purchasing food at the market, waiting at the laundromat, standing in line at the post office, visiting the library, browsing through records and books, or circling the neighborhood in a car looking for parking for what seems like an interminable length of time, may serve as the basis for an anonymous informant to claim criminal activity. So long as the informant claims to have been an eyewitness to a criminal act, the tip need not provide even a modicum of reliability as to the alleged illegality, even though the tip is communicated outside the physical presence of law enforcement personnel, asserted by an unknown individual who is unwilling or unable to provide identifying information, such as a telephone number, and whose veracity is unproven and unconfirmed.

The People in Argyris and DiSalvo claim that predictive information is unnecessary because of the anonymous informant's alleged personal observations of the claimed criminal activity. As this argument goes, the informant is reliable because in addition to describing the car and the defendants, the informant said that he saw one of the men put a gun in the back of the car.

My concurring colleague agrees, and offers four grounds to support her conclusion (see concurring op of Abdus-Salaam, J. at 1157-1162). First, as the People here contend, predictive information is but one way to establish basis of knowledge under the Aguilar-Spinelli test. As such, an anonymous informant may establish basis of knowledge by a statement of personal observation of illegal conduct, as is the case in these appeals.

The appropriate response to the People's argument is that of the dissent in Navarette to a similar claim of alleged personal observation. Reacting to the Navarette majority's assertion that the informant claimed to have been run off the road and therefore had eyewitness knowledge, Justice Scalia remarked, "So what?" (Navarette, 572 US at ___, 134 S Ct at 1693 [Scalia, J., dissenting]). For, "[t]he issue is not how [the informant] claimed to know, but whether what [the informant] claimed to know was true" (id.). To that question, "[t]he claim to `eyewitness knowledge' ... supports not at all its veracity" (id.).

A simple example, comparing a tip from an informant who claims to have personal eyewitness knowledge to alleged gun possession, with a tip from an informant who makes no such assertion, reveals the strained logic of the argument. A selfreferential statement of eyewitness observation of criminal activity, summed up in the words "I saw a gun," sheds no greater light on whether the informant is to be trusted and the tip relied upon, than does the same statement, from the same informant, but without the claim of having seen a weapon. In both scenarios, the police have only the informant's word as to what occurred, and no way to confirm it, without engaging in independent police investigation.

Accepting self-verification based on no more than the informant's bald unsubstantiated assertion goes against common sense because such statement proves nothing and adds nothing to the reliability analysis. It does, however, increase the risk of police intrusions based on fabricated information by legitimating police action that is based on an anonymous tip that says nothing more than "I saw something so I said something."2

My colleague's second ground for rejecting a requirement of predictive information is that the requirement supposedly fails to assist police in testing the truthfulness of the informant's account of the criminal activity prior to taking action against the subject of the tip. Yet, the fact that an anonymous tip may not provide police with reasonable suspicion of criminal activity is the very reason why courts demand more than unsubstantiated assertions from unknown persons. As has been the case for decades, where police receive an anonymous tip the police may determine, based on the content of the tip and police experience and expertise with anonymous informants, whether and how to follow up on the anonymous information. If, by independent investigatory police work and their personal observations, the police corroborate the readily observable, innocuous noncriminal information provided by the informant, and also confirm the basis for the informant's allegations of criminal activity, such that the police "believe criminal activity is at hand," the police may conduct an investigatory stop. If the police fail to confirm the tip, even under the lower threshold of reasonable suspicion, then they may not act. The fact that the police may be unable to corroborate an anonymous tip is a consequence of our society's choice to protect constitutional rights.

The third ground asserted is that predictive information will not eliminate the risk that malicious tipsters will fabricate reports of criminal activity, and may very well increase that risk. The reason being, that those most likely to have predictive information are those closest to the tipster's target, and they are as likely as anyone else to make up a story. Moreover, where the informant bears personal animosity towards the target, the informant may be motivated to lie. This is pure speculation and conjecture. The reality is that the tests for constitutional sufficiency of informant tips seek to reduce the possibility of fabrication by requiring information that is intended to permit police and courts to weed out the genuine tips from those motivated by a personal agenda. Police have a long history of distinguishing the malevolent from the honest informant. That task is made harder when the informant is anonymous, and thus requires that police have information to assist them in determining what is a genuine source of reliable information.

As a fourth ground, my colleague asserts that a predictive information requirement would place an excessive restraint on law enforcement, imperiling public safety. Of course, we do not want to interfere unduly with police work. The concern as explained, however, sounds like fearmongering. Even if members of the general public who observe a crime have no way of knowing what the subject of the tip will do and cannot provide predictive information, that does not mean, as posited, that serious crimes would go unpunished. Unlike my colleague I place my confidence in a law enforcement system that relies on the work of police officials, trained and experienced in investigatory techniques, familiar with the street hustles and the fake claims of imminent danger, rather than in unsubstantiated tips from anonymous persons.

Despite claims that the only way to avoid endangering the public and prevent the erosion of law enforcement is to cede our hard-fought rights to liberty and privacy, the truth is just the opposite. Police intrusion based on untested and uncorroborated claims of criminal conduct does not safeguard the public or encourage effective law enforcement. I reject the premise that it is simply too difficult for law enforcement to do what they are trained to do, and that it is too much to expect that those charged with protecting us will do so by applying their skills in accordance with constitutional and statutory requirements.

My concurring colleague, Judge Smith, opposes the application of the Aguilar-Spinelli test, and in its stead would apply the totality of the circumstances test (concurring op of Smith, J. at 1141, 1143). However, we rejected that federal approach in Johnson, finding our state constitutional standards better protected individual rights (see 66 NY2d at 407). That assessment of the totality test is still applicable today and I see no reason to reconsider and resuscitate a standard buried long ago.

III.

Some states and law enforcement have argued for years that tips about illegal guns should be treated differently, and absolved of the usual constitutional requirements of reasonable suspicion and probable cause (see e.g. J.L., 529 US at 271). We have never, at least until now, found support in fact or logic for such an exception to the general rule that police intrusions of liberty require a showing of reasonable suspicion to support an investigatory stop, or probable cause for a search and an arrest.

In J.L., the Supreme Court rejected such entreaties to carve out a "firearm exception" that would permit a stop and frisk based on a tip that would not otherwise provide a constitutionally justifiable basis for the stop (id. at 272). After recognizing that "[f]irearms are dangerous, and extraordinary dangers sometimes justify unusual precautions" (id.), Justice Ginsburg noted that the Terry rule sought to address these concerns by permitting a protective police search based on reasonable suspicion rather than probable cause. She then stated

She also recognized the difficulty of cabining such an exception to firearm prosecutions because, as Federal Circuits Courts of Appeals have found, it is "foreseeable for people carrying significant amounts of illegal drugs to be carrying guns as well" (id. at 273 [citations omitted]). She continued:

My colleagues go further because they would apply the totality of circumstances or Aguilar-Spinelli tests to all investigatory stops, not just those involving guns. Such approach risks the further watering down of rights in the future.

IV.

Turning to the instant appeals, in Argyris and DiSalvo, I would find that the anonymous tip lacked the indicia of reliability necessary to support reasonable suspicion to forcibly stop defendants. The informant provided descriptive information of the defendants, the car and van and the route they were taking when he last observed them. This information was readily observable to anyone on the street. The tip lacked predictive information as to the criminal activity alleged because the informant stated only that he had seen one of the men put a gun in the back of the car. Without more, the tip lacked information to establish the reliability of the allegation of gun possession.

To the extent my colleagues accept the veracity of the anonymous informant based on the informant's word they ignore the primary lessons of federal and state cases that anonymous tips are inherently suspect and cannot, on their own, serve as a basis for police intrusions. Equally unavailing is my concurring colleague's assertion that "[b]y claiming personal knowledge, the tipster puts his or her own credibility on the line rather than seeking to hide behind a secondhand hearsay source" (concurring op of Abdus-Salaam, J. at 1163). This completely fails to comprehend that because the informant is anonymous, there is no way to assess credibility unless the tip contains predictive information that affords police the ability to corroborate the substance of the tip. An anonymous source, immune from prosecution for false statements, places nothing "on the line."

Here, because the tip on its own was insufficient to provide reasonable suspicion, the police were left to investigate and determine whether additional information confirmed the tip. This is what several officers did, and this was good police work because they were able to corroborate the descriptive information by personal observation. However, before they could corroborate the allegation of gun possession Officer Valles stopped defendants' car at gunpoint. As the record makes clear, the only information known to Officer Valles when he initiated the stop was the contents of the tip: the descriptive information and the bare assertion of the presence of a weapon. Plainly, at this point, the police lacked reasonable suspicion to forcibly stop defendants' vehicle. Therefore, despite the majority's conclusion otherwise, there is no record support for the finding below (see majority mem at 1140). Indeed, even under a totality of the circumstances analysis, there are too few details in the aggregate to support a finding of reasonable suspicion (see id.; see also concurring op of Smith, J. at 1143). As a consequence, the subsequent search was unlawful and the evidence seized during the course of the search should have been suppressed (see William II, 98 NY2d at 100).

The anonymous tip in Johnson is also constitutionally deficient because it too lacked predictive information about the alleged criminal activity of driving while intoxicated, and the police failed to observe conduct that would suggest the tip was reliable. Based on slightly different legal grounds I agree with the majority that County Court should be reversed and the motion for suppression granted. I, therefore, concur in the result.

V.

My colleagues accept a standard below any constitutional floor this Court has ever recognized. In so doing they reject Moore without legal justification or good reason. They also conveniently disregard our long-standing interpretation of our State Constitution's expansive protections (see e.g. People v Weaver, 12 N.Y.3d 433, 445 [2009]), and ignore the concerns about anonymous informants expressed in our prior case law. In my opinion, we must remain ever mindful of this Court's statement in Elwell, regarding the power of the State to arrest, and which applies with equal force to lesser police intrusions, that reliance "on mere suspicion collides violently with the basic human right of liberty. It can be tolerated only in a society which is willing to concede to its government powers which history and experience teach are the inevitable accoutrements of tyranny" (Elwell, 50 NY2d at 236 [citation omitted]). I dissent.
