Second Guessing

What was his homelife like, we ask.  How did other children treat him when he was a kid?  What was the final trigger?

It's not really a blame game.  It's a prevention tactic--an attempt to figure out how to avoid a future tragedy, an attempt to make sense out of the senseless, to reassure ourselves we can establish control over the uncontrollable.

Better gun control will help, better school security will help, a kinder society will help, but, ultimately, we are at an impasse because there's no way to predict where the next threat will come from. Who can chart the course of a human brain?
