Yes. I was just having that conversation with my partner as we drove through the George Floyd memorial yesterday afternoon, that was set up by protesters on the spot where George Floyd was murdered by police officers. It was a heart-wrenching shrine they set up.
She made the comment that is both true and ironic how that the most progressive cities, have the most red, abusive police forces. I think psychologically there is a reason for that, as police forces, especially the one here with their far-right policy union, attract those who are bullies to wear a badge. Think of it like how the priesthood attracts pedophiles. It's a place for them to hide out and shield them from their proclivities and illegal activities.
Progressive cities which are diversity friendly, are seen as a threat by those who are stuck at that stages of "otherism", and segregationism. So those who feel powerless, seek places for where they can act out on their agressions as bullies, legally. Such an environment, attracts these to itself.
Of course there are good cops, those who legitimately seeking to "protect and serve", just like you have good priests too. But if the environment is a "band of brothers", where they protect their own, just like in the priesthood, the bad apples can hide out.
