Back in 2019 the police in Fresno stole a bunch of rare coins during a search of a house where the warrant did not cover anything like said coins, valued at $125,000, by reporting that they seized $50,000 when they actually took twice that much in cash and the coins. The 9th Circuit ended up deciding that while it was obviously morally wrong, qualified immunity applied because there's clearly established case law that stealing property that was specifically targeted for a search does violate the Constitution, because there's no analogous case regarding property stolen by police that the police did not know was there and are not covered by the warrant, there's no clearly established violation of the 4th Amendment even though it is literally an unlawful seizure of property. Supreme Court denied cert, allowing the decision to stand. I wish I was joking.
