BINGOAdding I'd like to see a law specifying that the FALSE assertion that something was "PROHIBITED" could be charged against the owner of the property!
A private property owner can post all the signs they want, and if they see you carrying they can ask you to leave. You will not be charged for carrying in a prohibited area, but you can be charged for Trespassing if the owner chooses to do so. You have a defense that your presence was not impacting their business but it's a defense not a guaranteed get out of jail free. But they have broken no law in doing so.
So were this Theater not a state entity location yes they could prohibit. Depending on the lengths they wish to go to they could enforce their prohibition or rely on good behavior. But to say they can't prohibit is false. Thus my initial statement about the ownership of the Theater is accurate and pertinent. SLC cannot declare the theater off limits, nor can they attempt to enforce any such restriction. A privately owned theater could declare it off limits and could attempt to enforce their prohibition. Not with legal charges until you refused to leave, but they can still attempt to enforce, and once you refuse to leave then they can resort to Trespass charges to enforce.
Thus when the Jazz (under orders from the NBA) states that personal fire arms are prohibited at the Vivint arena, they are not guilty of any crime. Neither are you if you attempt to ignore their rule. But if they catch you and you don't remove the weapon or leave when asked then they can legally Trespass you.
