WATCH: Teacher threatens student on camera

ROCKFORDALE, Ga. – A video is going viral of a teacher threatening a student in class.

Paul Hagan, a physics teacher at Rockdale Career Academy, was caught on camera ranting to a black student.

You can hear Hagan telling the student, “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.”

Now the kid’s mom wants the teacher to be fired.

She started a petition and filed a police report to press charges.

The school is now investigating.
