There is no "reasoning" for this, other than a "show of force". I guess that's why I refuse to spend my money at wallyworld. Anyone that is THAT against self-defense can piss up a rope. They would have rather had those employees die from gunshots, than defend themselves and live to see the sunlight of tomorrow! What's WRONG with you people? I don't care WHO I work for, if I have a chance to disarm a gunman and live to see tomorrow, "F" the friggin' job!
