It's sad that this guy went on a rampage. Too bad they couldn't spot him before he did it. It sounds like there might've been some clues.
It's weird that he himself was a psychiatrist. But anyone can have mental problems, and he obviously had them aplenty.
I'm hoping that the right wing crazies don't generalize this into a religious war, as though all folks of his religion (Muslim) are somehow responsible. That's ridiculous and I hope we're smarter than that.
It's extremely unfortunate, the whole stinking thing.
