What is the test for overturning a finding of probable cause under a search warrant?

The determination of whether probable cause exists for the issuance of a search warrant requires an examination of the "totality of the circumstances" to determine whether "there is a fair probability that contraband or evidence of a crime will be found in a particular place." Illinois v. Gates, 462 U.S. 213, 238 (1983). ¹ "The [reviewing] court may not reverse a magistrate's finding of probable cause unless it is clearly erroneous." United States v. Schmidt, 947 F.2d 362, 371 (9th Cir.1991).

A district court's denial of a motion to suppress is reviewed de novo. United States v. Negrete-Gonzales, 966 F.2d 1277, 1282 (9th Cir.1992). Factual findings at the suppression hearing are reviewed for clear error. Id.
