Before this descends in to the usual suspects going back and forth like every other thread, I am very happy that apparently both of the shooters in these incidents were captured alive.
I have always wished that some of these people could be caught rather than committing suicide/being shot by police like they usually are. Firstly, it will be interesting to hear what was going through their head (through media interviews or psychiatric examinations).
Secondly, I think it lessens the appeal for others that might want to try this in the future. It's a lot more romantic to go out in a hail of bullets than it is to spend a few decades in jail while being excoriated in the popular culture for the selfish, cowardly, evil scumbag that you are and dealing with the families of the innocent people you killed. I think if these people are publicly vilified while they are still alive, it might make others less likely to follow in their footsteps.
