I have had several incidents that resulted in exposing that I was carrying and they do happen. In one, a store clerk bumped into me as we were looking up to see if there was product on the top shelf. It caused my shirt to rise enough to see it AND she felt it. She looked at me and said, "Shhh, my dad carries too." That could have gone south, quickly. 2. Civil Liability vs Criminal. A person comes in to a no carry place, robs it. You, fearing for your life kill them. In most states YOU are now (a) criminally liable because you created a Criminal Trespass situation and (b) you are going to end up in a civil court after the first guilty verdict and be sued for everything you have because they criminal element runs in the family and they don't care of Jr. was robbing the place and threatened you. You were guilty and no lawyer is going to plead out a civil for less that most of what you own for the next 50 years. Best thing to do is let the manager know you did not spend any money there because of their policy. If they accumulate enough complaints and losses they might rethink it. But pushing the anger buttons doesn't help anything.
