A federal judge on Thursday struck down rules set for protesters at next month’s Republican National Convention in Cleveland. Ohio’s branch of the American Civil Liberties Union brought the suit last week against the city of Cleveland, arguing that restrictions on protesters within the “event zone” around Quicken Loans Arena are unconstitutional. Those restrictions would ban certain items, including large backpacks, tape and string, and limit where within the 3.5 square mile zone demonstrators can speak and hold a parade.
