It ain't complicated at all. The Gun industry marketed to the worst kind of people. Tragedy ensued. Um... no. Here's the thing. In a society where we DON'T LET CRAZY PEOPLE HAVE GUNS, it doesn't matter if he goes off the rails or not. I mean, yeah, maybe he'd have shown up with a baseball bat or something, but they'd have been able to easily overpower him. NOpe. Growing up in a house with no guns in it would have prevented this tragedy.
