Sample:
Jessop v. City of Fresno. In this case, the Ninth Circuit granted immunity to police officers who stole over $225,000 in cash and rare coins in the course of executing a search warrant. The court noted that while “the theft [of] personal property by police officers sworn to uphold the law” may be “morally wrong,” the officers could not be sued for the theft because the Ninth Circuit had never issued a decision specifically involving the question of “whether the theft of property covered by the terms of a search warrant, and seized pursuant to that warrant, violates the Fourth Amendment.”
The police department has its own separate claim against the officer, of course, for the costs they have incurred (separate from the value of the stolen property, which wasn't theirs to begin with) as a result of the officer's actions.
