It doesn’t matter what state you are in or whatever their laws, walk down the street with a firearm in view and unless you are a uniformed guard or policeman someone will call 9/11 in short order and police will pounce.You will be lucky not to be shot by them if you don’t obey their orders fast enough.
According to the story he had the firearm stuffed under his shirt, but apparently in a manner so that it was visible. Then he walks into a bank, goes to a teller window, writes a note and says “gun”. He’s lucky to alive, imho.
Ever been to NM or AZ? I've walked down the street in both states wearing a firearm in full view, and no-one even noticed, much less called the cops.
