I don't give a [bleep] who or what color you are. We are a Nation of laws and if a cop says STOP, DROP, get down, hands up or whatever during a time that you're doing something wrong--and you know when that is--- then you do so and you stay there until you see your lawyer. PERIOD.
Otherwise, face the consequences of being an azzhole/dumbass.
Should this have gone to trial? Maybe.
Should the perp have done what he was told during his wrong and with no resist? Oh hell yeah!
