one side, there remains sufficient content in the warrant affidavit to support a finding of probable cause.... ” Franks, 438 U.S. at 171-72, 98 S.Ct. 2674.
The district court in this case refused, after reviewing the affidavit at issue and Archuleta’s motion and supporting materials, to conduct an evidentiary hearing. More specifically, the district court concluded that Archuleta failed to establish “that Detective Lane made a false statement in any manner at all, much less, knowingly and intentionally, or with reckless disregard for the truth,” and that “even if the Court were to so find, the allegedly false statements [we]re in no way necessary to the finding of probable cause.” ROA, Vol. I, Doc. 26 at 9.
To date, we have not expressly indicated what standard of review applies to a district court’s refusal to conduct a Franks hearing. “[T]he [other] circuits are split as to the proper standard of review” on this issue. United States v. Stewart, 306 F.3d 295, 304 (6th Cir.2002). Some “employ [a] clear error” standard of review. Id.; see United States v. Buchanan, 985 F.2d 1372, 1378 (8th Cir.1993) (employing clear error standard); United States v. Skinner, 972 F.2d 171, 177 (7th Cir.1992) (same); United States v. Hadfield, 918 F.2d 987, 992 (1st Cir.1990) (same); United States v. One Parcel of Property, 897 F.2d 97, 100 (2d Cir.1990) (same). Others apply a de novo standard of review. Id.; see United States v. Gonzalez, Inc., 412 F.3d 1102, 1110 (9th Cir.2005) (applying de novo standard); United States v. Martin, 332 F.3d 827, 833 (5th Cir.2003) (same). We conclude it is unnecessary to resolve the issue in this case because, for the reasons outlined below, we would affirm the district court’s under either standard of review.
a) Alleged false statements in the supporting affidavit
Archuleta contends that the affidavit prepared by Detective Lane and submitted in support of the request for the search warrant contained two false statements. First, Archuleta contends that the affidavit falsely stated that the confidential informant who spoke to Officer O’Donnell identified Archuleta as the “shooter” in the Brookside Park shooting. In support of this contention, Archuleta points to a subsequent affidavit that Detective Lane prepared in support of a search warrant for the home of another suspect named Alex Wenger. In that affidavit, Detective Lane noted that several citizens voluntarily provided information to the authorities regarding possible suspects in the Brookside Park shooting, and that a “confidential informant of Officer O’Donnell of the Farmington Street Crimes Unit ... contacted Officer O’Donnell within two hours of the shooting” and “identified three suspects by name as Alex Wenger, Jeremy Archuleta, and Nathan Archuleta.” ROA, Vol. I, Doc. 13 at 5 (emphasis and italics added). According to Archuleta, this statement undercuts the veracity of Detective Lane’s statement in the first affidavit that the confidential informant identified Archuleta as the “shooter.” Accordingly, Archuleta contends that the first affidavit should have read, as did the subsequent affidavit, that the confidential informant “identified three suspects by name as Alex Wenger, Jeremy Archuleta, and Nathan Archuleta.”
We conclude that Archuleta has failed to make a substantial showing that Detective Lane’s reference in the affidavit to Archuleta being identified as the “shooter” was false, much less that Detective Lane knowingly and intentionally, or with reckless disregard for the truth, used the term knowing it was false. As noted by the government in its response to Archuleta’s
