The police will sometimes, in the routine execution of their duty, have to pin someone down. I don't recall any evidence that the murder was intentional. There is an expectation that the police are the sort of people who could kill someone if the need arises. They aren't all going to be philosophers.
Given that and the vitriol around the situation, it is quite reasonable for the police to close ranks around him and look to the most charitable interpretation of what happened. The courts exist to sort out such situations, the police don't need to become vigilantes as well.
