Simply put, you'd be quite inbalanced to think guns should be banned. This Cho fuck may have got it legally, but he brought it ILLEGALLY into a guns-free zone. Anyone crazy enough to want to kill someone will find a way to do it. If he didn't get ahold of a gun, he would have made a bomb or found another way. Why take away the last defense another human has? If I couldn't have a gun and there was a shooter near, I'd be left to dial 911 or hope for the best. Really, people with this point of view are moronic.
