The teacher was obviously trying to establish who the dominant one was. The student should have defended himself. People just don't have the balls to throwdown these days.
on the one hand the teacher did something she shouldn't have (hell something no one should do). on the other hand with proper parenting a child won't be laughing at the less fortunate (not the stuff of integrity). so really we've got two fuck ups parents and a teacher.
Totally unbalanced report - nothing from the teacher involved, they did not even try to get a comment, if they had they would have said something like "she failed to comment". Little brat probably provoked it. Everyone has a breaking point.
