Insightful post.
I have a personal experience with this kind of kid who is just like the kind who does this stuff. He threatens, is creepy, flouts the rules and makes death threats. but his parents think he is bullied,,,he is not, he is shunned.
When he is caught, his parents intimidate the school to get him off and then he ups the bad behavior. He will kill someday, I have no doubt.
But he isnt just a weird kid who doesnt fit in. He is a psychopath.
The pics I have seen of him reminds me of the Muzzy terrorists with their thousand mile stare of death.
