Cops aren't supposed to deal out punishment because someone "deserve it". They are supposed to arrest people, who can then be put on triel, and their ponishment can be decided.

The knee to the throat seems to be a pretty stupid thing to do to keep someone at the ground, but i suppose that it is possible that it was the easiest way to keep him at the ground.

Going from holding his hands, to hitting him in the head seems mindnumbingly stupid. I fail to see how it can serve any other purpose than inflicting pain on the guy lying down. Actually it will propably make him resist even harder.
