The only thing that could be changed is the involuntary commitment laws and I do not see that happening. Even if they did and you could hold someone until they were deemed better once they get out they stop taken their drugs and the ride starts all over again.

I seem to remember something about a building blowing up in OK city. They were sane and did not use guns . How about suicide bombers . There are 1000s of ways to kill many people at once , the only thing you need is the motivation. I think it scares people that there is no real solution. Your kids are safer in school than they are in your car .
