to be honest, I've been in an argument all day with a coworker on this one.
In no way do I justify what he did and I believe justice is now served with what he got. BUT I will say there is supposed evidence of him reaching out to his mother before all of this took place and saying he needed help, and that she might not ever see him again. He was in MASSIVE debt, multiple times having been evicted etc etc etc. The man clearly had some serious mental issues/chemical imbalances. He wasn't a teenager or anything, he's been milling around in public for a long time. Someone somewhere dropped the ball here I believe, as this man had to have shown signs of mental instability long before this happened.
Again I in no way justify what he did or how he handled his issues, and he definitely got what he deserved.
