I'll put this to you - people of color are absolutely justifiably fearful of any interaction with the police, and they have to experience it much more frequently. You need a source? Here - https://www.nytimes.com/interactive/2020/06/03/us/minneapoli... Hope you'll read it.
And this includes ALL white people, much less "white people who happen to be police officers". My argument is not saying police brutality doesn't "exist", I'm saying it's "overblown".
Finally, I am a "person of color" myself and I don't find the police behave to me in the way you describe. They don't act that way towards my father either, not even once in his life. Or any of my person-of-color friends for that matter. Admittedly, this is anecdotal, but my main point is the overall data does not point towards your premise.
