Byars v. United States

State police officers obtained a search warrant for the defendant’s residence from a judge. However, the warrant was invalid as it clearly lacked probable cause. Nonetheless, a search for “intoxicating liquors and instruments and materials used in the manufacture of such liquors” was authorized. A Federal prohibition agent was asked to participate in the search, which he did. During the search, the Federal agent found some counterfeit whiskey stamps, while a State officer found additional counterfeit stamps. The counterfeit stamps were seized and the defendant was arrested.
