All public schools need to be able to expel students. Teachers should not have to put up with disrespectful, obnoxious thugs. Any student that mouths off to a teacher, administrator, security, etc., should just be booted from school. Frankly, I don't care what happens to them after that. Maybe prison will do them some good. Good kids shouldn't have their education ruined by a minority of students. If kids saw there were real consequences for their behavior, others might learn from watching what happened to their thug friends.
