I agree. I haven't seen a case where it happened yet, but eventually one of these idiots is going to whip out the "evil black assault rifle" in the cafeteria and a student or faculty member who is illegally carrying will end his reign of terror. I hope it never happens, but I would love to see how the anti-gun movement twists that one around. All the numbers I have seen show that guns save more lives than they end.
A hit with a .45 ACP beats a hit with a .22 LR everytime. A hit with a .22 LR beats a miss with a .50 BMG everytime.
