Defendant Rodney Woosley entered a conditional plea of guilty to knowingly and intentionally possessing marijuana with intent to distribute, in violation of 18 U.S.C. § 841(a)(1), and to possession of a firearm in furtherance of a drug trafficking crime, in violation of 18 U.S.C. § 924(c)(1)(A). On appeal, Woosley argues that the district court should have granted his motion to suppress evidence seized during a search of his business, on the ground that the warrant authorizing the search was issued without probable cause. Because we conclude that the warrant was supported by probable cause, we affirm the judgment of the district court.

On or about August 15, 2001, Kentucky State Trooper Christopher Armbrust applied for a search warrant for Woosley's business premises. In support of his application, Trooper Armbrust prepared an affidavit on a pre-printed form. The form identified Woosley's business, Quick Lube Plus, as the premises to be searched and specified that the contraband sought included marijuana, firearms, and other items related to marijuana trafficking. The warrant application further provided that Trooper Armbrust received information from

[a] confidential informant whom [sic] is known to the affiant to be credible and reliable, who has provided accurate information in the past which has been shown to be truthful and reliable. This informant stated to the affiant that on [August 15, 2001] they observed approximately five pounds of processed marijuana under the desk of the Owner Rodney Woosley. Also present were two firearms which they described as Handguns possibly 9MM.

Trooper Armbrust averred that he had previously received tips from "numerous independent informants" that indicated drug trafficking was occurring at the Quick Lube Plus and that he had received similar information from an officer at the local police department.1

Trooper Armbrust telephoned the county attorney and asked her for advice concerning the sufficiency of the affidavit. She opined that the affidavit was sufficient to support the application for a search warrant. Trooper Armbrust met with a state district judge, who issued a search warrant. During that meeting, Trooper Armbrust did not orally supplement the information set forth in the affidavit.

Trooper Armbrust promptly executed the search warrant and discovered marijuana, small amounts of other drugs, and two pistols at Woosley's place of business. In a two-count indictment, Woosley was charged with knowingly and intentionally possessing marijuana with intent to distribute, in violation of 18 U.S.C. § 841(a)(1), and with possession of a firearm in furtherance of a drug trafficking crime, in violation of 18 U.S.C. § 924(c)(1)(A).

Woosley filed a motion to suppress the evidence found during the search, arguing that the affidavit supporting the search warrant did not establish probable cause and that the warrant was not executed in good faith. The district court denied the motion to suppress, finding that the affidavit alleged facts sufficient to establish probable cause. At his change of plea hearing, Woosley entered a conditional plea of guilty, pursuant to Federal Rule of Criminal Procedure 11(a)(2), reserving his right to appeal his motion to suppress evidence. Woosley also moved for a hearing under Franks v. Delaware, 438 U.S. 154, 98 S. Ct. 2674, 57 L. Ed. 2d 667 (1978).2 The district court issued an order denying Woosley's motion for a Franks hearing and accepting his conditional plea. Woosley filed this timely appeal.

The district court correctly concluded that Trooper Armbrust's affidavit was sufficient to establish probable cause because, considering the totality of the circumstances, the affidavit contained sufficient information to permit the issuing judge to make an independent determination of probable cause.3 "In order for a judicial officer to issue a warrant, law enforcement officials must present evidence from which the magistrate judge can conclude from the totality of the circumstances, `including the "veracity" and "basis" of knowledge of persons supplying hearsay information, there is a fair probability that contraband or evidence of a crime will be found in a particular place.'" United States v. Williams, 224 F.3d 530, 532 (6th Cir.2000) (quoting Illinois v. Gates, 462 U.S. 213, 238, 103 S. Ct. 2317, 76 L. Ed. 2d 527 (1983)).

This court reviews the sufficiency of an affidavit to determine "whether the magistrate had a substantial basis for finding that the affidavit established probable cause to believe that the evidence would be found at the place cited." United States v. Davidson, 936 F.2d 856, 859 (6th Cir.1991) (quotation omitted). The affidavit should be reviewed in a commonsense — rather than a hypertechnical — manner, and the court should consider whether the totality of the circumstances supports a finding of probable cause, rather than engaging in line-by-line scrutiny. United States v. Greene, 250 F.3d 471, 479 (6th Cir.2001). The magistrate's determination of probable cause is afforded great deference, and that determination should be reversed only if the magistrate arbitrarily exercised his discretion. Id.

In United States v. Allen, 211 F.3d 970 (2000) (en banc), which is relied on by both Woosley and the Government, we held that

where a known person, named to the magistrate, to whose reliability an officer attests with some detail, states that he has seen a particular crime and particular evidence, in the recent past, a neutral and detached magistrate may believe that evidence of a crime will be found.

Id. at 976 (emphasis omitted). In concluding that independent police corroboration of the information provided was unnecessary in such cases, we emphasized that probable cause determinations must be based on the totality of the circumstances and cautioned against a continuing reliance on formalistic "tests" that required the satisfaction of particular elements to support a finding of probable cause. Id. at 975-76.4 Consequently, an affidavit including a tip from an informant that has been proven to be reliable may support a finding of probable cause in the absence of any corroboration. See id. at 976; United States v. Smith, 182 F.3d 473, 478-79 (6th Cir.1999). Alternatively, an affidavit that supplies little information concerning an informant's reliability may support a finding of probable cause, under the totality of the circumstances, if it includes sufficient corroborating information. See Illinois v. Gates, 462 U.S. 213, 241-45, 103 S. Ct. 2317, 76 L. Ed. 2d 527 (1983); United States v. Tuttle, 200 F.3d 892, 894 (6th Cir.2000) ("[I]nformation received from an informant whose reliability is not established may be sufficient to create probable cause when there is some independent corroboration by the police of the informant's information."). Thus, the question is whether the instant affidavit, which contains little basis for the state court judge to assess independently the informant's credibility, otherwise includes sufficient corroboration that the state court judge could determine, under the totality of the circumstances, that probable cause existed.

Woosley complains that the affidavit did not contain sufficient information regarding Trooper Armbrust's confidential informant to permit the magistrate to make an independent evaluation of probable cause.5 Trooper Armbrust's affidavit stated:

[a] confidential informant whom [sic] is known to the affiant to be credible and reliable, who has provided accurate information in the past which has been shown to be truthful and reliable. This informant stated to the affiant that on [August 15, 2001] they observed approximately five pounds of processed marijuana under the desk of the Owner Rodney Woosley. Also present were two firearms which they described as Handguns possibly 9MM.

. . . .

Previously the affiant received information from numerous independent informants information which indicates that Drug Trafficking is occurring at this location. The affiant also has information that marijuana is packaged in parts boxes specifically alternator boxes.

The affiant also has spoken with Sgt. Jeffrey W. Hart of the Morganfield Police Department who also has information that Marijuana is trafficked out of this business and usually leaves the business in computer parts boxes.

While additional details about the confidential informant may have been helpful, "[t]he affidavit is judged on the adequacy of what it does contain, not on what it lacks, or on what a critic might say should have been added." Allen, 211 F.3d at 975. Here, Trooper Armbrust, who had received information about drug dealing from Woosley's business location in the past, received a tip from a known, credible and reliable source. The tip identified the contraband with great specificity and described its particular location with precision. Trooper Armbrust then spoke with a local law enforcement officer, who confirmed that he had received similar reports. A magistrate could conclude, based on the totality of the circumstances described in the affidavit, that there was a fair probability that contraband or evidence of a crime would be found at Woosley's business. Accordingly, the warrant issued for Woosley's business was supported by probable cause.

Finally, we decline to consider Woosley's additional contention that the district court erred in denying his motion for a Franks hearing, because his conditional plea only reserved the right to appeal the district court's ruling — entered September 10, 2002 — denying his motion to suppress. Federal Rule of Criminal Procedure 11(a)(2) provides that a criminal defendant, with the consent of the Government and the court, may enter a conditional plea, reserving in writing the right to appeal adverse decisions of specified pre-trial motions. Woosley's motion for a Franks hearing was not part of his motion to suppress, and it was not disposed of in the district court's September 10, 2002, order. Accordingly, Woosley may not appeal the district court's adverse ruling on his motion for a Franks hearing, as he did not reserve his right to appeal that issue.

Because the warrant authorizing the search of Woosley's business was supported by probable cause, the judgment of the district court is AFFIRMED.
