What is the test for obtaining a warrant to search a person's home?

The remaining goal of the statute, to protect an occupant's privacy interest, was also satisfied by the police conduct in this case. First, they obtained a warrant; its very existence necessarily casts some limitations on an individual's right of privacy. Second, defendant's home was not suddenly or violently invaded; the police knocked on the door and politely requested admittance. Finally, the police were peaceably admitted; thus there was no danger of "unexpected exposure of private activities." (United States v. Bustamante-Gamez (9th Cir.1973) 488 F.2d 4, 12.)
