Shot In A "Gun-Free Zone"

What part of the body is that? Oh; you mean where guns are not allowed? How’s that workin’ out for ya, huh? In Inglenook, Alabama, a recently fired former employee went into a UPS facility and shot three people to death, before killing himself. How is this POSSIBLE? I thought “gun-free zones” guaranteed our safety within them. I guess they don’t, after all. But will the anti-gun fools take note of this? Doubtful. They’re probably the only people who don’t have to worry about being shot in the head. There isn’t a bullet strong enough to get through their thick skulls. Will they ever learn? No. They’re too stupid. (CNN)
