I'm not sure we can say this is a race thing as much as a "cops are assholes" thing. I mean the white guy with the same name got dragged out of the car and held at gunpoint in a similar situation.

Once things get past a certain point, the system is loath to simply say "we made a mistake and we apologize", because they wrongly believe that admitting fault will somehow lessen people's respect for them. I think this mistaken belief that they're protecting the system overall is behind a lot of really fucked up rulings by judges excusing absolutely outrageous behavior by cops.

In fact it's the opposite, admitting your mistakes and making amends is a sign of maturity and legitimacy. Making a bad situation worse by punishing someone unjustly instead of just backing down when you're at fault is what actually undermines faith in the system.
