Tis funny how everyone wants to ban certain types of guns. A firearm doesn't function on its own. The weak link is humans, period.
Banning guns will only accomplish having the psychos use alternate means to bring about thier plots. More people are injured or killed by small arms fire ( handguns) than all the rest combined. There are nearly 4 times the handguns produced than rifles and it has been that way for a long time.
There will always be the disturbed freaks that are going to do what they are going to do, be it with guns, explosives, poisons or whatever else they can dream up.
