have idea, quit spouting NRA dogma and prove your theory that what you propose would happen. Neither you nor I have any idea what would happened. Suppose law enforcement saw a "responsible" student shooting the actual gunman. That student would have been gun down. As the video taken by a student clearly showed law enforcemetn having shootout so the gun fire was clearly not over. Would be nice if people look at facts rather than make thier arguement based on facts not your personal belief. This type of argument is stupid. What has to happen is that a rational non-bias investigation needs to occur. ----- Its already happened. Appalacian law school students run to their cars, get their guns and hold shooter at bay. IIRC, in Kentucky, A teacher gets his gun out of his car to gets a 15 year old shooter to disarm. Its funny the media never talks about these cases. Can I say bias?
