How much do you really know about what happened at the school? Not much I would gather from your comments. My son goes to that school and he said the student who hit the teacher is in a "special" class and he hit the teacher by accident. The student was trying to hit another student. Not that that changes what happened, but it's not like the student went after the teacher. The student threw the chair at another student and the chair bounced around and hit several other students
