I said punish them only if they put bans on worker safety when they have CCW laws. They should be as liable as if they had no fire exits/alarms and the place burns down. IMO, it’s basic negligence.
Or would you take the position that if a person is going to break the law with a gun, there's very little you or a security guard can do to stop him. He'll simply shoot the security guard first, right? In either case, I don't believe you can hold a business liable for someone else's actions.
