Retaliatory arrest for filming police?

PORTLAND, Maine — A federal court in Maine partially denied two police officers’ motions to dismiss First Amendment claims brought against them by a man who “frequently films police conducting public arrests in and around Brunswick, Maine.” It would be reasonable to find that the man was arrested on one occasion in part because he was filming. An officer told him, “You’re getting a citation today for being on a limited access highway as a pedestrian. You’re out on 295 filming.”
