You are obviously a cop apologist. One: the cop had no business sticking his hand over the guys mouth, actually it looks as if he actually stuck it inside the guys mouth. Two: the cops hand was out of the guys mouth after the first blow so why did he keep on hitting the guy? Three: the cop was wearing gloves so there is no way in hell the guy bit the cop hard enough to draw blood. There were three other cops holding this guy all they needed to do was handcuff him and toss him in a squad car. Why didn't they and why were they holding him and hitting him to begin with? What led up to that?
All of these officers should be fired.
