California has a law that effectively prohibits firearms dealers from displaying the image/likeness of a firearm on signs advertising their shops. Several firearms businesses and individuals sued the State (Kamala Harris as AG, in particular) in federal court for summary judgment against violation of their First Amendment protected right to speech. The State opposed asking for summary judgment in favor of their law. Plaintiffs won in district (trial) court.
