This is still just othering police, and thereby avoiding solving any problem. I.e. if the problem is caused by some inherent factor in the people who choose to become police officers, then we can simply blame them and move on; easy hate clicks galore!

But I think police are molded by their experiences, and made by various vicious cycles to become the stereotypical bad police. I described one such cycle above; here is another: http://tailsteak.com/archive.php?num=545 If this is correct, then anybody, even the most well-meaning angelic people, would, over time, become bad police, but anyone could still merely claim that all police are bad because they are “right-wing” (as if that automatically is a bad thing) or racist, and nothing could ever be solved.

Police are also moulded by politics, they answer to someone, which usually isn't the locals. Consider Louisville, KY, where there have been demonstrations for 3 months now against the Breonna Taylor shooting, with no visible results. Such an environment attracts a certain kind of person, with a predictable outcome.

I would assume that the cycle of police recruitment and retirement is too slow to have this big of an effect. To affect police behavior, the iteration cycle must be fast (which I assume it isn’t), or the pressure must be huge (which we should have seen evidence of, I would think, since the large disparity between boss and subordinate would create some leaks).
