In Georgia, Rockdale County Public Schools has fired physics teacher Paul Hagan after he was caught on video apparently threatening a student in class. "If you screw with me, you're going to be in big ass trouble," he says in the video. "Don't smile at me, man. That's how people like you get shot. I got a bet by the time you're 21 somebody's gonna put a bullet right through your head. Okay? And it might be me the one who does it."
