You bring up a good point, Kimba, in the 1 on 1 gangland style attack, on another student/gangmember, vs what this legislation is more designed for, the prevention of mass killings, at the hands of a dedicated murderer, operating in a so called "gun free zone". The former probably doesn't get the attention it deserves. I mean, look at Chicago...murders by guns, every day, though I'm not sure many of those are on school grounds, yet you hardly hear a peep in the news. But if a Sandy Hook gets hit, its 24/7 news.
Bottom line, is the more legal folks are trained and in a position to stop a wound be assassin/killer, the less lives lost while everyone is waiting for the police to arrive...with their guns
