Before LUCERO, SEYMOUR, and MURPHY, Circuit Judges.


SEYMOUR, Circuit Judge.
      Eric Michael Madrid appeals his conviction on one count of being a felon

in possession of a firearm in violation of 18 U.S.C. § 922(g)(1). Mr. Madrid pled

guilty to the charge but preserved his right to appeal the district court’s denial of

his motion to suppress evidence. For the following reasons, we AFFIRM.

                                          I.

      At 7:53 p.m. on November 4, 2007, an operator with the Sandoval County

Communications Section received a 911 call from an unidentified male tipster.

The caller reported that he was in the parking lot of the Rinaldi Apartments in

Bernalillo, New Mexico, and that there was suspicious activity occurring. He

said there were two cars and two men and a woman in the parking lot. He

reported that the two men were arguing and “getting into each other’s faces,” and

that it looked like the men were about to fight. The caller told the operator that

his fiancée was supposed to arrive shortly and he was afraid to leave her in the

parking lot alone. He described one of the two vehicles as a white, four-door

Pontiac and described the clothing of the men who were arguing. He said he did

not see any weapons. As he was talking to the 911 operator, the caller saw police

cars drive past the entrance to the parking lot. He told the operator that when the

police cars passed by the suspects began “scattering” and the white Pontiac was

leaving the parking lot.

      Lt. Stoyell was dispatched to the Rinaldi apartments at 7:55 p.m. Officers

Sanchez and Marshall were dispatched one minute later. A dispatch operator

                                         -2-
conveyed to the officers by radio that a 911 call had originally reported a

suspicious subject but subsequently changed the report to a fight. The dispatcher

advised the officers that there were two males and a female arguing in the parking

lot and relayed the description of the vehicles and clothing given by the caller.

Lt. Stoyell and Officer Marshall arrived at the apartments at 7:57 p.m. Lt. Stoyell

stopped the white Pontiac and Officer Marshall stopped the other vehicle.

Lt. Stoyell shined his spotlight on the Pontiac and waited for backup to arrive.

Officer Sanchez arrived about a minute later, parked his vehicle alongside Lt.

Stoyell’s, and shined his spotlight through the front windshield of the Pontiac.

      Lt. Stoyell approached the driver’s side of the Pontiac while Officer

Sanchez approached the passenger’s side to provide cover and to determine

whether anyone else was in the car. Lt. Stoyell recognized the driver as Mr.

Madrid, whom he knew from prior encounters. Lt. Stoyell had executed a search

warrant on Mr. Madrid’s home about a month earlier, and he knew that Mr.

Madrid had recently been released from the penitentiary and was a convicted

felon. Officer Sanchez also recognized Mr. Madrid from prior investigations and

was aware he was a convicted felon.

      Lt. Stoyell advised Mr. Madrid that he was investigating a possible fight

and asked what had been going on in the parking lot. Mr. Madrid replied that he

and his companions had not been fighting, but had just been talking. Lt. Stoyell

then requested Mr. Madrid’s license, registration and proof of insurance, which he

                                         -3-
provided. At about this time, Officer Sanchez looked through the passenger side

windows of the car and saw a rifle case on the back seat. He believed it was

likely the case contained a rifle and he told Lt. Stoyell there was a rifle in the car.

Lt. Stoyell requested that Mr. Madrid exit the car for officer safety reasons, patted

down Mr. Madrid, and handcuffed him.

      Meanwhile, Officer Sanchez removed the rifle case from the car, noticed it

was heavy enough to contain a rifle, and saw the rifle when he opened the case.

Officer Sanchez then went to assist Officer Marshall for about five to seven

minutes when he was told one of the passengers in the other car had an

outstanding warrant for her arrest. When Officer Sanchez returned to the Pontiac,

he spoke with Lt. Stoyell, secured the rifle, and checked to see if it was stolen.

      Lt. Stoyell notified Mr. Madrid that he could be charged with being a felon

in possession of a firearm and asked if he would be interested in working off the

charge by cooperating with the police in other investigations. Mr. Madrid agreed

to cooperate, so Lt. Stoyell released him but kept the rifle for evidence. The

officers did not file a report on the incident because Mr. Madrid had indicated he

was interested in cooperating. When Mr. Madrid’s cooperation did not

materialize, the officers eventually proceeded with the felon-in-possession case

against him.

      Mr. Madrid was indicted by a federal grand jury on one count of being a

felon in possession of a firearm, and one count of possessing a firearm after

                                           -4-
having been convicted of a misdemeanor domestic violence offense, in violation

of 18 U.S.C. §§ 922(g)(1), 922(g)(9) and 924(a)(2). Mr. Madrid filed a motion

to suppress the rifle. The district court held an evidentiary hearing and denied his

motion. Mr. Madrid subsequently pled guilty to the felon-in-possession count

pursuant to a plea agreement in which he reserved his right to appeal the district

court’s denial of his motion to suppress.

      Mr. Madrid filed a notice of appeal on October 19, 2009, three weeks after

the ten-day period to appeal had expired. He subsequently filed a motion under

Federal Rule of Appellate Procedure 4(b)(4) to extend the time in which to file

his notice of appeal, claiming excusable neglect. The government moved to

dismiss the appeal based on the late filing, but the district court granted Mr.

Madrid’s motion. The government then moved this court to dismiss Mr. Madrid’s

appeal, which we did, holding that his notice of appeal was untimely and that his

error did not constitute excusable neglect. United States v. Madrid, 

, 1227-28 (10th Cir. 2011). On December 27, 2011, Mr. Madrid filed a

motion to vacate, set aside or correct his sentence under 28 U.S.C. §2255. The

district court granted the motion in part, finding that Mr. Madrid’s trial counsel

was ineffective for failing to file a timely notice of appeal. The court vacated its

original judgment and reentered it so that Mr. Madrid could file a timely notice of

appeal, which he did on June 6, 2012.




                                            -5-
                                         II.

      Mr. Madrid contends the district court erred in denying his motion to

suppress, asserting the evidence against him resulted from an investigatory stop

that lacked reasonable suspicion in violation of the Fourth Amendment. In

reviewing the denial of a motion to suppress, “[w]e view the evidence in the light

most favorable to the government and review the district court’s factual findings

for clear error. We review the district court’s ultimate determinations of

reasonableness under the Fourth Amendment de novo.” United States v. Tucker,

, 1199 (10th Cir. 2002) (internal citations and quotation marks

omitted).

      The Fourth Amendment protects “[t]he right of the people to be secure in

their persons, houses, papers, and effects, against unreasonable searches and

seizures . . . .” U.S. Const. amend. IV. It is well established that “[t]emporary

detention of individuals during the stop of an automobile by the police, even if

only for a brief period and for a limited purpose, constitutes a ‘seizure’ of

‘persons’ within the meaning of [the Fourth Amendment].” Whren v. United

States, 

, 809-10 (1996). In Terry v. Ohio, 

 (1968), the

Supreme Court established a two-pronged test to determine the reasonableness of

investigatory detentions. For an investigatory detention to be reasonable it must

be “justified at its inception” and the officer’s actions must be “reasonably related

in scope to the circumstances which justified the interference in the first place.”

                                         -6-
Id. at 20. The only issue in this appeal is whether the seizure of Mr. Madrid was

justified at its inception.

       Under Terry and its progeny, “the police can stop and briefly detain a

person for investigative purposes if the officer has a reasonable suspicion

supported by articulable facts that criminal activity ‘may be afoot,’ even if the

officer lacks probable cause.” United States v. Sokolow, 

, 7 (1989)

(citing Terry, 392 U.S. at 30). “An investigatory detention is justified at its

inception if the specific and articulable facts and rational inferences drawn from

those facts give rise to a reasonable suspicion a person has or is committing a

crime.” United States v. McHugh, 

, 1255 (10th Cir. 2011) cert.

denied, 

 (2011) (internal quotation marks omitted). We evaluate

the totality of the circumstances to determine whether “the detaining officer had a

‘particularized and objective basis’ for suspecting legal wrongdoing.” Cortez v.

McCauley, 

, 1123 (10th Cir. 2007) (quoting United States v. Arvizu,

, 273 (2002)). “[T]he ultimate assessment of reasonable suspicion

depends on the totality of the circumstances [and] [i]n making that determination,

a court may not evaluate and reject each factor in isolation.” United States v.

Gandara-Salinas, 

, 1130 (10th Cir. 2003) (citing Arvizu, 534 U.S.

at 274-75).

       Police officers must have more than a “hunch” to justify stopping an

individual, but “the likelihood of criminal activity need not rise to the level

                                          -7-
required for probable cause, and it falls considerably short of satisfying a

preponderance of the evidence standard.” Arvizu, 534 U.S. at 274. We have held

that “as long as [the detaining officer] has a particularized and objective basis for

suspecting an individual may be involved in criminal activity, he may initiate an

investigatory detention even if it is more likely than not that the individual is not

involved in any illegality.” United States v. Johnson, 

, 1194 (10th

Cir. 2004) (emphasis in original). We apply an objective standard to determine

whether the “facts available to the officer at the moment of the seizure or the

search [would] warrant a man of reasonable caution in the belief that the action

taken was appropriate.” Terry, 392 U.S. at 22 (internal quotation marks omitted).

Due to their “experience and specialized training,” we “accord deference to an

officer’s ability to distinguish between innocent and suspicious actions.”

Gandara-Salinas, 327 F.3d at 1130. “Moreover, reasonable suspicion may be

supported by an objectively reasonable good faith belief even if premised on

factual error.” United States v. Vercher, 

, 1261 (10th Cir. 2004)

(internal quotation marks omitted).

                                          A.

      Mr. Madrid first claims the district court clearly erred in finding Lt. Stoyell

was unaware that a physical fight had not actually transpired in the Rinaldi

Apartments parking lot when he detained Mr. Madrid. To be clearly erroneous,

“a finding must be more than possibly or even probably wrong; the error must be

                                          -8-
pellucid to any objective observer.” Watson v. United States, 

, 1108

(10th Cir. 2007). “[W]e will reverse the district court’s finding only if it is

without factual support in the record or if, after reviewing all the evidence, we are

left with a definite and firm conviction that a mistake has been made.” Keys

Youth Services, Inc. v. City of Olathe, 

, 1274 (10th Cir. 2001)

(internal quotation marks omitted).

      Mr. Madrid cannot meet this high standard. The 911 dispatcher informed

Lt. Stoyell in the minutes before he stopped Mr. Madrid that two men “may be

starting a fight,” that “two males are yelling at each other and [are] in each

other’s face right now,” and that dispatch had changed the code from “suspicious

subject” to “fight.” See Supp. Rec. vol. I at 1. While it is true that only a couple

of minutes elapsed between the unknown caller reporting a fight was imminent

and Lt. Stoyell arriving on the scene, an argument can escalate to a physical fight

in a matter of seconds. Accordingly, there is sufficient evidence to support the

court’s finding that when Lt. Stoyell stopped Mr. Madrid, he was unaware a

physical fight had not actually occurred.

                                            B.

      Mr. Madrid also asserts the court should not have considered Mr. Madrid’s

attempted exit from the parking lot in its reasonable suspicion analysis because

neither police officer specifically testified he believed Mr. Madrid was fleeing the

parking lot in order to evade the police. The subjective beliefs of the detaining

                                            -9-
officers, however, are irrelevant. “An action is reasonable under the Fourth

Amendment, regardless of the individual officer’s state of mind, as long as the

circumstances, viewed objectively, justify the action.” Brigham City v. Stuart,

, 404 (2006) (internal quotation marks and brackets omitted)

(emphasis in original). Both this court and the Supreme Court have held that a

suspect’s unprovoked flight and other evasive behavior upon noticing police

officers is a pertinent factor in determining reasonable suspicion. See Illinois v.

Wardlow, 

, 124 (2000); accord United States v. McHugh, 

, 1258 (10th Cir. 2011). Accordingly, the district court did not err in

considering Mr. Madrid’s attempted exit from the parking lot just after a police

car drove by in its reasonable suspicion analysis.

                                         C.

      Mr. Madrid further contends the district court erred by failing to take into

account the relatively minor nature of the crimes being investigated in assessing

whether Lt. Stoyell had reasonable suspicion to stop him. “Following the

Supreme Court’s approach in Henley, we determine the constitutionality of an

investigatory stop by balancing ‘the nature and quality of the intrusion on

personal security against the importance of the governmental interests alleged to

justify the intrusion.’” United States v. Moran, 

, 1141 (10th Cir.

2007) (quoting United States v. Hensley, 

, 228 (1985)).

      Regarding the “nature and quality of the intrusion” on Mr. Madrid’s

                                         -10-
personal security, “[a]n investigatory stop is by definition ‘brief’ and ‘non-

intrusive.’” Id. at 1143 (quoting United States v. Johnson, 

, 1188

(10th Cir. 2004)); see also United States v. Griffin, 

, 1516 (10th Cir.

1993) (explaining that a Terry stop is “usually characterized as a brief,

nonintrusive detention”). Here, the officers stopped Mr. Madrid’s car, shined

their lights through the windows for officer safety reasons, and requested his

license, registration, and proof of insurance. This was no more intrusive than an

ordinary traffic stop. The detention was prolonged only because probable cause

subsequently developed for the officers to believe that Mr. Madrid was a felon in

possession of a firearm.

      In addition, the government’s interest in “solving crimes and bringing

offenders to justice . . . [was] particularly strong [because] the criminal activity

involve[d] a threat to public safety.” Moran, 503 F.3d at 1142. The impetus for

the 911 call that led to the investigatory stop was the caller’s worry for the safety

of his fiancée, whom he believed would be threatened because it appeared that

Mr. Madrid was about to engage in a physical fight in the parking lot. When the

stop was initiated, Lt. Stoyell did not know whether a fight had in fact occurred or

whether anyone had been injured. As we explained in Moran, “the governmental

interest in solving crime may be weaker when police have alternative methods of

investigating the crime,” id., but here no such alternative methods were

reasonably available. Given an objectively reasonable belief that a fight had just

                                          -11-
occurred and the participants were “scattering,” a brief investigative stop of a

suspected participant in the fight who was attempting to leave the scene would be

the most logical and one of the only plausible investigative methods to pursue.

And as we further stated, there is a stronger governmental interest in stopping “an

individual in the process of violating the law or a suspect fleeing from the scene

of a crime than a suspect in a past crime who now appears to be going about his

lawful business.” Id. at 1143 (internal quotation marks omitted); see also id. at

1142 (“[B]ecause [the defendant] had allegedly committed the [crime] just

minutes before the officers stopped him, the governmental interest in solving the

crime was strong.”).

      In sum, the intrusion on Mr. Madrid’s personal security was brief and

minimal, and the government had a strong interest in solving crime and ensuring

public safety in the circumstances the officers faced here.

                                         D.

      Finally, Mr. Madrid claims the district court erred both in determining that

the anonymous 911 call was reliable and in finding that the tip gave rise to

reasonable suspicion to stop his vehicle. “A confidential tip may justify an

investigatory stop if under the totality of the circumstances the tip furnishes both

sufficient indicia of reliability and sufficient information to provide reasonable

suspicion that criminal conduct is, has, or is about to occur.” United States v.

Leos-Quijada, 

, 792 (10th Cir. 1997); accord United States v.

                                         -12-
Samuels, 

, 1191 (10th Cir. 2007); see also Florida v. J.L., 

, 270 (2000) (“[T]here are situations in which an anonymous tip, suitably

corroborated, exhibits sufficient indicia of reliability to provide reasonable

suspicion to make [an] investigatory stop.”) (internal quotation marks omitted).

      The determination of “[w]hether a tip provides reasonable suspicion to

make a traffic stop is case-specific,” and no single factor is dispositive. United

States v. Chavez, 

, 1222 (10th Cir. 2011).

      [R]elevant factors include: (1) whether the informant lacked “true
      anonymity” (i.e., whether the police knew some details about the
      informant or had means to discover them); (2) whether the informant
      reported contemporaneous, firsthand knowledge; (3) whether the
      informant provided detailed information about the events observed;
      (4) the informant’s stated motivation for reporting the information;
      and (5) whether the police were able to corroborate information
      provided by the informant.

Id.; accord United States v. Copening, 

, 1247 (10th Cir. 2007)

(considering these factors and concluding information from unidentified 911

caller was sufficiently reliable to establish reasonable suspicion); United States v.

Brown, 

, 1078-79 (10th Cir. 2007) (same); see also J.L., 529 U.S. at

274 (Kennedy, J., concurring) (“[T]here are many indicia of reliability respecting

anonymous tips . . . .”).

      Turning to the first of these factors, “[u]nlike a tip from a known informant

whose reputation can be assessed and who can be held responsible if her

allegations turn out to be fabricated, an anonymous tip alone seldom demonstrates


                                         -13-
the informant’s basis of knowledge or veracity.” J.L., 529 U.S. at 270 (internal

quotation marks and citation omitted). In United States v. Johnson, 

 (10th Cir. 2004), we further explained that “[a] tipster who refuses to

identify himself may simply be making up the story, perhaps trying to use the

police to harass another citizen.” Id. at 1190. On the other hand, jeopardizing

one’s anonymity creates “disincentive for making false allegations.” United

States v. Jenkins, 

, 554 (10th Cir. 2002). See also Copening, 506

F.3d at 1247 (“The fact the caller provided authorities some basis for discovering

his identity makes it less likely his tip was phony.”).

      The government argues that the unidentified caller here was not truly

anonymous because he was likely in the parking lot or nearby when officers

arrived on the scene and officers could have questioned bystanders to determine

who had placed the 911 call. The government also asserts it is likely that either

the caller or his fiancée lived in the apartment complex, which may also have

enabled police officers to identify him. Although the caller did not give his

name, the 911 operator never requested it. It is unclear from the record whether

or not the number he called from was blocked, but we will assume, arguendo, that

it was.

      The characteristics of the call highlighted by the government do make the

caller marginally less “truly anonymous” than the unrecorded tip made from an

unknown location in J.L., where the informant failed to provide any information

                                         -14-
about himself or the basis for his knowledge. See J.L., 529 U.S. at 268 (holding

an anonymous, undocumented and unrecorded telephone call indicating a young

black male in a plaid shirt standing at a particular bus stop was carrying a gun,

without more, was unreliable and therefore insufficient to justify a Terry stop of

the defendant). It is quite possible, however, that the caller left the parking lot

once he saw Mr. Madrid and his companions leaving the scene and the police

arriving, because he no longer needed to worry for his fiancée’s safety. That

would leave only the assumption that the caller or his fiancée might live in the

apartment complex to support the possibility the police could identify the caller.

Neither the size of the Rinaldi apartment complex nor the number of residents is

established in the record.

      Our cases addressing this issue have presented significantly more

information about the identity of the unnamed caller. For example, in United

States v. Brown, 

 (10th Cir. 2007), a 911 caller did not provide his

name but did relate that he was a friend of the alleged victim and was present

when an armed man entered the alleged victim’s apartment. We distinguished

this tip from the truly anonymous caller in J.L. because “[a]lthough the police did

not know the caller’s name . . . they knew enough about him to reasonably believe

they could locate him had his call been simply intended to harass [the

defendant].” Id. at 1076. Similarly, in Chavez, “although the caller did not

provide dispatchers with his name, he told them he was a Wal-Mart employee at a

                                         -15-
specific Wal-Mart store and thereby provided the police with information to

discover his identity.” 660 F.3d at 1222; see also United States v. Torres, 

, 212 (3d Cir. 2008) (although 911 caller did not give his name, the fact

that he told dispatcher he was driving a green cab for a specific taxi company

“further supported the reliability of his tip”). As we explained in Brown, “[a]n

unnamed individual who divulges enough distinguishing characteristics to limit

his possible identity to only a handful of people may be nameless, but he is

capable of being identified and thus is not anonymous.” 496 F.3d at 1075.

      The scant information officers had regarding the unnamed caller in the

instant matter is a far cry from the identifying information police had in Brown

and Chavez. Nor is the information about the caller comparable to cases where an

unnamed informant called 911 from an unblocked phone number. See Copening,

506 F.3d at 1247 (holding 911 call from unblocked cell phone number supported

reasonable suspicion for investigative stop where caller refused to give his name,

in part because “[t]he caller should have expected that 911 dispatch tracks

incoming calls and that the originating phone number could be used to investigate

the caller’s identity.”). The tenuous possibility that the police could have

identified the 911 caller in the instant matter falls closer to the truly anonymous

tip in J.L. than to the unnamed but not truly anonymous calls in cases like

Chavez, Brown and Copening.

      To assess the reliability of a tip, however, we must examine “the totality of

                                         -16-
the circumstances—the whole picture,” Sokolow, 490 U.S. at 8 (internal quotation

marks omitted), and “no single factor is dispositive.” Chavez, 660 F.3d at 1222.

A 911 caller who offers only “minimal” identifying information—that he was at

or in front of an address across the street from where shots were fired—is not

“completely unidentifiable;” giving the address was at least an “indicium of

reliability.” Robinson v. Howes, 

, 829 (6th Cir. 2011). Here, the

911 operator never asked the caller for his name or other identifying information

and there is no reason to believe he would not have provided this information if

requested. See Torres, 534 F.3d at 212 (investigative stop supported by

reasonable suspicion based, in part, on anonymous 911 call in which “the tipster

neither attempted to, nor had any reason to, conceal his identity; the dispatcher

simply neglected to ask him his name”). And there is no indication the caller was

“making up the story, perhaps trying to use the police to harass another citizen.”

Johnson, 346 F.3d at 1190; see also Easton v. City of Boulder, 

,

1449 (10th Cir. 1985) (“[T]he skepticism and careful scrutiny usually found in

cases involving informants . . . from the criminal milieu, is appropriately relaxed

if the informant is an identified victim or ordinary citizen witness.”).

      Significantly, all of the other factors that we consider to determine whether

a tip provides reasonable suspicion support the caller’s reliability. First, it is

clear the caller was reporting contemporaneous, firsthand knowledge of the

possible fight in the parking lot. As we stated in Brown, “[w]e consider it another

                                          -17-
important indicium of reliability that the caller claimed firsthand knowledge of

the alleged conduct.” Brown, 496 F.3d at 1076. Here, as in Brown, because “the

officers knew that the caller’s information was based on firsthand knowledge and

that it was contemporaneous[,] [t]hey were reasonable . . . in taking the caller’s

information more seriously than information obtained, for instance, through the

report of a third party or reported sometime later than the described events.” Id.

at 1077.

      Second, the caller provided detailed information about the events he was

observing, including describing the clothing and automobiles of the individuals

involved in the incident. This is another indicium of reliability that we have

recognized in our reasonable suspicion analysis of anonymous tips. See, e.g.,

Copening, 506 F.3d at 1247 (unnamed caller’s “detailed description” of the

alleged criminal activity “bolstered the tip’s reliability.”).

      Third, the caller’s stated motivation for calling 911 and reporting the

possible fight was a concern for his fiancée’s physical safety. This stated motive

further buttresses the reliability of the information related by the caller because it

reduces the possibility that he harbored animosity towards defendant or his

companions and tends to show that he was not using “the device of a phoney tip

to wreak injury (indignity, invasion of privacy, suspicion, and sheer annoyance)

on [his] enemies, rivals or acquaintances without fear of being held responsible.”

United States v. Hauk, 

, 1188 (10th Cir. 2005); see also Copening,

                                          -18-
506 F.3d at 1247 (stating “an ordinary citizen acting in good faith” in calling 911

indicates reliability); Brown, 496 F.3d at 1077 (“[W]e consider it important that

the caller’s primary motive in contacting 911 . . . was not to implicate the armed

man but to obtain aid and protection for his friend.”).

      Finally, police officers dispatched in response to this call were able to

verify much of the information the caller had provided. Although the caller’s

description of the possible criminal activity of the suspects was not verified by

the officers, as they arrived at the scene they did find the two cars matched the

descriptions given by the caller, and also that the suspects were in their vehicles

and attempting to leave, just as the caller had described. As we recognized in

Copening, “[t]he officer’s corroboration of the latter information, lent credibility

to the former. This is particularly true where . . . the caller’s asserted basis of

knowledge—as to both types of information—was first-hand and real-time

observation.” Copening, 506 F.3d at 1247; see also Chavez, 660 F.3d at 1222

(tip’s reliability was bolstered by fact that police officers verified some of

information caller provided about suspect’s non-illegal conduct before making

Terry stop).

      There was no need here for the caller to exhibit “inside knowledge” of the

alleged crime because he was not an informant providing a tip about a concealed

weapon or contraband based on insider information. He was instead a concerned

citizen witnessing a situation in public view that he thought was about to become

                                          -19-
a crime and a threat to public safety, who then reported the disturbance to the

authorities. See United States v. Perkins, 

, 325 (4th Cir. 2004)

(distinguishing between tips regarding alleged possession of concealed firearms

that “may require corroboration of the extent of the tipster’s inside information,

in order to ensure that the tipster was in a position to know about the alleged

illegal conduct” and tips “where the suspicious activity is openly and readily

observable, [where] other manners of corroborating a tip are entirely legitimate”);

accord United States v. Wheat, 

, 734 (8th Cir. 2001) (“Unlike with

clandestine crimes such as possessory offenses, . . . where corroboration of the

predictive elements of the tip may be the only means of ascertaining the

informant’s basis of knowledge, in erratic driving cases the basis of the tipster’s

knowledge . . . comes from his eyewitness observations, and there is no need to

verify that he possesses inside information.”); see also United States v. Wooden,

, 650 (7th Cir. 2008) (“A 911 system designed to provide an

emergency response to telephonic tips could not operate if the police had to verify

the identity of all callers and test their claim to have seen crimes in progress.”);

Cf. J.L., 529 U.S. at 270-71 (explaining that an anonymous informant would need

“inside knowledge” of a suspect for their tip to be reliable regarding “hidden

contraband”).

      Mindful of the “skepticism and careful scrutiny” required in the

anonymous-informant context, Copening, 506 F.3d at 1247, we conclude,

                                          -20-
considering the totality of the circumstances, that the caller’s tip bore “sufficient

indicia of reliability to provide reasonable suspicion to make the investigative

stop” of Mr. Madrid. J.L., 529 U.S. at 270 (internal quotation marks omitted).

The 911 call and corroborated facts provided Lt. Stoyell with a particularized and

objective basis for suspecting Mr. Madrid had just been involved in criminal

activity. Accordingly, the investigative stop was justified at its inception and was

not in violation of the Fourth Amendment.

      We AFFIRM.
