What if you simply refuse to answer any questions and tell them to eff off? What can they do? Detain you indefinitely at Club Fed in Guantanamo Bay, Cuba?
What they would do is “trespass” you, effectively banning you from the MOA for however long they wish. That’s what they do if they discover one is leagally carrying a handgun with a carry permit. By law, they cannot post the MOA ,but they do anyway. Individual tennants may post their store, if they so choose. None do. So, they just kick you out and tell you never to return.
