Messerschmidt v. Millender, handed down today, by the U.S Supreme Court.

Girlfriend is moving out of place where she lived with boyfriend, a Crips member with a very long rap sheet. He attacks her, tries to throw her from a second floor landing. She speeds away while he fires five shots at her from a sawed-off shotgun. She reports situation to police, adding that boyfriend might be staying at the house of his stepmother.

Police get a warrant to search stepmother’s place for all firearms and gang-related material, and execute it, seizing a shotgun that belonged to the stepmother. She sues under 42 USC 1983, apparently arguing that (1) the warrant called for searching and seizing all firearms, when only one, of a specific known appearance, had been used in crime and (2) there was no probable cause to search for gang-related things.
