Read the yahoo article earlier on this guy. At first, it just seemed funny that this guy somehow ended up on stage with our President faking hand signals.
But after reading the article, he's a messed up dude. Schizophrenic. Involved in a murder with three others in which they "necklaced" a guy which I had never heard of. It involved tying a tire around a guys neck and then setting it in fire to kill him.
