I think the difference may be whether the "posted" property is open to public use. In other words, if it's my house, then I have the right to post it AND if you violate that, I CAN have you arrest for trespassing. In the case of an area open to the public, they can just ask you to leave first, then if you refuse, get you arrested. But I've also seen those type of signs at the social security office in Pueblo. They specify that having a CCW DOES NOT exempt you. They don't have a metal detector, but they do have an armed guard. I still carry anywhere I can get away with it. :P :twisted: :P Karl.
