On what basis? The cop did not break any federal law. He should have been more careful, but he was just trying to do his job. Apparently, it is a job he is not competent for. If I were his boss, he would be fired.
Maybe the police should have thrown a net over the perp? Of course, then they would be accused of racism because they would be treating him like some sort of jungle animal. Is it to the point that they should say “Pretty please...”?
