I donno if I would say kids gloves. This dude is not going to see the light of day. But I have noticed what you said and I wonder if they (the feds) want to study these individuals, which I happen to agree with. I think understanding why a seemingly intelligent, normal person who has no criminal record would do something so seemingly random is important.
I think just writing off as evil is counter productive to identifying individuals who have the potential to do something like this before something like this happens.
