This guys is just a sociopath. A lot of the children killed were in Kindergarten? Just heard that the shooter evidently killed his parents before doing this. Absolutely horrible. My condolences to all of the people effected by this. I can't imagine the situation they are in.
First report I saw said a pair of 9mm handguns were found, nothing about AR-15's or anything "crazy"...
Don't know what goes through peoples heads to make them do something like this. I had the nearly uncontrollable urge to grab a nice bum the other day, but I stopped myself... You'd think somewhere along the line of these peoples "plans" they'd say to themselves that something's FUCKED UP.
They always are, and the question becomes what can we (if anything) do about it to try and prevent such senseless acts of violence. We don't have a particularly great mental health system here in the U.S., but I'm not convinced these types of things would go away even if we did. Just a terrible, terrible, event.
