In the eyes of the administration, there is no evidence that any student was physically threatening. Nor did the teacher do what he was supposed to do to maintain order. In order to have a good school, there must be a minimal level of complaints from those people that the administration has no contol over: the parents. Obviously, in this situation, the teacher is clearly at fault for not performing to the schools' standard procedures. Following proper procedure leads students by example and creates a better learning environment. When a teacher does not follow established procedure, it sends students the signal that it's OK to rebel against authority. SO if there are problems in the classroom, it's becasue of the disruptive nature of the teacher. < /sarcasm>
Personally, I hope more teachers bring many more lawsuits against their incompetent administrators.
