The following excerpt is from USA. v. Sayakhom, 186 F.3d 928 (9th Cir. 1999):
The warrant was not overbroad. A generalized seizure of business documents may be justified if the government establishes probable cause to believe that the entire business is merely a scheme to defraud or that all of the business's records are likely to evidence criminal activity. See United States v. Kow, 58 F.3d 423, 427 (9th Cir. 1995). The items described in the warrant were sufficiently connected to the allegations of mail fraud described in the indictment.
