I agree the officer was a little over the top flipping her out of the chair. However, why do teachers or authority figures need to prove to students that they are making efforts?? The kids need to learn to respect authority when they are told to do something. Babying them and patting them on the back a thousand times is not going to get the point across, all that will do is teach them to stay stubborn and insubordinate until they get they want.
