then what exactly is going to be the deterrent against criminals with guns that want to cause a massacre? are these people supposed to just say 'hey man, dont shoot me pls k tnx' and be on their way? fact is, if people want guns, the law wont stop them from getting a gun if they really want it, and only others carrying a gun will be enough to stop anyone looking to take as many lives as they can in any given setting.
