My side of this is simple, don't go into a place where you are unwanted, if you are AWARE, that you are unwanted. If you're caught, what is your excuse? You entered a place of your own free will that you knowingly knew you were unwelcome. It's hard to complain about being disarmed and dismissed when you're the one causing the probelm.
Ummm, my excuse is my life has been threatened by a drug addicted psychopath.
The hospital will not provide armed guards to walk with me.
