The following excerpt is from U.S. v. Hand, 61 F.3d 913 (9th Cir. 1995):
Although the informant appears to have been acting as a government agent and there was no valid justification for his warrantless entry, his actions did not taint the warranted search. The police had applied for a warrant to search the hotel room and submitted their evidence of probable cause to the magistrate before the illegal entry occurred. Accordingly, the original warrant was clearly untainted. See Murray v. United States, 487 U.S. 533, 542 (1988) (warranted search is untainted if the officers' decision to seek a warrant is not prompted by the illegal entry and if no information obtained during that entry is presented to the magistrate).
