Fired, facing civil litigation, and possible jail time to come.
Fired but I doubt any jail time or civil litigation....in fact he'll likely be reinstated as the other teacher was for breaking up a fight by using a broom. He used his belt to break up a fight and prevent injuries so it falls under the Good Samaritan Law
If the teacher was a white man, he'd be charged with hate crimes, get sent to prison and the kids would all get invited to the White House.
