while yes, they may have been protecting them selves from other people with guns, how much do you want to bet the people who were the ATTACKERS and not the people who were protecting them selves got those guns illegally?
also do you really think that if there were virginia tech students who were legally allowed to carry a side arm and had proper training that those shootings wouldnt have turned out any different? the fact that it's known that people may return fire alone is a huge deterrent. i would love to hear of ONE mass shooting that happened in a area that open carry/concealed carry is allowed. those teachers at the school were guns aren't allowed sure didn't have a chance.
The problem with the VT incident is this
Those are the two weapons used, and the guy who didnt it didnt give a shit if he lived or died. He wanted to kill as many people as possible, so he would have done it if people had guns or not.
Without access to those to hand guns, there would be no reason to arm people to protect them selfs against people who have those.
The logic here is making me ill.
