Although I don't agree with TAB, you guys gotta understand that he's being literal. When he says "if you violate company policy, you should be fired," he IS NOT saying, "if you carry a gun and defend yourself, you should be fired."
Personally, I think Cosmoline hit the nail on the head, policy-wise, but TAB is correct in his line of thinking, and technically speaking, it doesn't exclude necessarily the employee carrying or using a gun to effect personal defense.
C'mon folks, TAB may not hold the same ideals as some of us, but he did not say that he wished that people would follow the rules to death.
