Killings in the mall in Nebraska

The killings in the mall of Nebraska happened yesterday. The comment one reported made from the letter of the killer bothered me. The killer said something like "I was a piece of shit, and now I will be remembered." This is sick and stereotypical. I've heard and seen in movies people thinking that doing something that makes TV/news is how you can be remembered. This kid was sick in the head. These type of children are out there and being displayed as sick in the head chilldren. Seriously they should not be in the public. There was signs in the case, way before the killing, that the kid should have been in a hospital because he was dangerous. The stepmom when interviewed after the killings try to make the boy just seem like he was out of his mind and just depressed. If you look more into the story, this wasn't his first incident. He was crazy. The psycho/depressed children are very dangerous.
