Is the violence more about mental health and less about gun control?

On a different note...I'm guessing the shootings in NYC put to rest the idea that armed civilians in Aurora would have helped the situation. Trained police officers shot and injured 9 bystanders in a shoot-out with a suspect. It was a clear day. I believe that had civilians with guns been in that movie theater the casualty count would have tripled.

It does for me, but I have few illusions that it will be so for others. The narrative will be "See, the police failed! In New York by the way."
