Bloomington Transit has a sign posted inside its busses that lists all the prohibited items on the bus, including "unauthorized weapons." I assume by "unauthorized" they mean non-LEO weapons. Though I have not asked so maybe authorized includes LTCH holders. But I have a hard time believing that. It's Bloomington. Anyway...is public transit allowed to post a sign prohibiting carry by licensed individuals? Obviously private business can with no force of law. If someone OC's on the bus and they try to tell them they can't board, would it be a violation of state law since it's public transportation?
