There is a chilling effect in the other direction as well. I'm not too keen on decorating my car to support various things I do support (candidate/BLM/etc) because I know the cops might treat me worse with that on my car... fun times.
I just have two Seattle Mariners bumper stickers on my truck; haven't been pulled over since putting em on, so they must think I have enough misery as it is!
/s I think the real issue is that it has been decided somehow that it is our fault for being policed and experiencing the frequent resulting injustices. A police officer can pull you over, stop you walking down the street, etc. etc. and fine you, jail you, or brutalize you at will, and in all but the most egregious cases (that also must become a cause celebre), they can just do it again tomorrow. There's always some justification, no matter how flimsy! That's not to say this violence is evenly distributed among the population. POC, the poor and working class, those who work odd hours and have to drive at 3 AM etc. certainly have a much, much, much harder time than e.g. the median HN commenter. But the answer to the question "What's stopping a given police officer from e.g. breaking my arm while pulling me out of my vehicle?" is much less "they will suffer consequences if they do" and much more "they haven't decided it's what they want to do today"
