Dalton police say Jesse Randal Davidson, 53, a social studies teacher and a play-by-play football announcer at the school, fired the shot. During his planning period around 11 a.m., police said Davidson locked himself in the classroom.

“When the principal put a key in the door to try to unlock the classroom, Mr. Davidson apparently fired a shot from a handgun to an exterior window of the classroom. It doesn't appear it was aimed at anybody,” Bruce Frazier, with the Dalton Police Department, said.

I wouldn't be surprised if this was deliberate, done to scuttle the armed teachers argument. Since he wasn't shooting AT anyone, I bet he plea-bargains to a misdemeanor and serves most of the time doing community service lecturing about not bringing guns to school. It could be a good career move for him after a few years. Hat tip to PawPaw.
