I'm 100% certain you have no idea how difficult it is. I'm firmly on the side of understanding there is blame both ways here. The cop was fired and I agree with that. The girl should be punished by the school. However, I'm trained in how to safely restrain and deal with violent and aggressive and non-aggressive students/people. It is much more difficult than you think. The cop made some huge mistakes here and did not follow the proper steps. He is facing the consequences. I know you said without 'throwing a desk' which is pretty specific. Your tone suggests you could do it without it looking violent at all. You could not.
