Sometimes you have to do what you are told....
Thomas Hobbes: "...men have no pleasure (but on the contrary a great deal of grief) in keeping company where there is no power able to overawe them all. For every man looketh that his companion should value him at the same rate he sets upon himself, and upon all signs of contempt or undervaluing naturally endeavours, as far as he dares (which amongst them that have no common power to keep them in quiet is far enough to make them destroy each other), to extort a greater value from his contemners, by damage; and from others, by the example.
So that in the nature of man, we find three principal causes of quarrel. First, competition; secondly, diffidence; thirdly, glory."
When the cops come, and you say, "I'm not going anywhere..." well, you are in fact going somewhere. And for the people who think that it was unecessary to send three policemen...the whole POINT of the state is to overawe the citizens, to make resistance futile, impossible.
The video above is not an abuse of state power, but rather its essence. This is what the state does, and it is ALL that the state is capable of: raw violence, overwhelming force, and putting a knee in your back while you are being handcuffed.
For my own view:
1. The instructor is partly, maybe mostly, at fault. You have to control the classroom by directing the subject away personal attacks. The student actually has a good point: the only reason this escalated was that the instructor insisted on having a whiny public argument, in class. Sure, the student was out of control. But this didn't have to happen. I have to admit some sympathy for the student here.
2. On the other hand, the student obviously thinks that rules don't apply to her. Look, folks, you should be afraid of the state, terrified in fact. The power of the state is limitless, and the first concern of the state is preserving the power of the state. No one is particularly concerned about you, except you.
