What is the scope of an inspection warrant?

We need not address this broad issue, however, as the facts here require us to do no more than determine the legitimate breadth of the warrant issued by the district court. In determining the validity of a criminal search warrant, we are limited to the information and circumstances that were available to the issuing officer at the time the warrant was issued. United States v. Brown, 455 F.2d 1201, 1204 (9th Cir.), cert. denied, 406 U.S. 960, 92 S.Ct. 2069, 32 L.Ed.2d 347 (1972). Applying this principle here, the proper scope of the inspection warrant is to be determined by considering the information presented to the district court in the warrant application.
