Hearing about this shocked and saddened me greatly. One of my sons is in kindergarten, and all I could think was that I wanted him home, right now. I can't imagine what all the affected families are experiencing.
I agree with a post made awhile back about needing to focus more resources on mental health. In nearly all incidents like this, the perpetrators are severely schizophrenic, yet they often get treated like evil criminal masterminds by the justice system, if they survive long enough to enter it. I'm not going to enter the gun control debate, except to say that I've never heard of a crisis of this scope being terminated by an armed vigilante. When I spend time in Churchill, however, I don't go outside without someone in my group carrying something big to deter polar bears. There's a line somewhere, but I have no idea where it ought to be drawn.
