I'm a white person and I think most all cops are assholes. I filed a police report with one a month or two back, his IQ couldn't have been much higher than 80, when I got a copy of the report he still got wrong the thing I corrected for him 3 times, and he still had an attitude despite the fact when we first met was me trying to figure out how to get in and he was basically the parking attendant.
At the same time, its very easy to see how cops can get prejudiced quickly when a disproportionate amount of their calls have to do with one race compared to another. Has nothing to do with one color of the skin being inherently superior to another, has to do with how things turned out the past 300 years and economics.
The question to me is how to best make reparations to even the playing field, and I don't know the answer. But generally speaking in the professional world, the affluent black guy is almost always the most likable guy in the room.
