Moreover, I'm also skeptical of the simplistic idea that our policing problem derives from "too many immoral officers". It seems more likely that it's an emergent property of the incentives and constraints we put on police brass (including the police union system).

Further, if we're going to reform police, it would be nice if we focused on policies which weren't predictably counter-effective. Rather than the de-policing policies which have increased homicides by 9k/year (relative to the time period before the de-policing movement kicked off in earnest with the largest increases in the "communities of color" in whose name the de-policing initiative campaigned) for no appreciable difference in unjustified police killings, it would be nice if we instead pursued one or more of: more police training, weakened/abolished police unions, restructured internal-affairs departments, tightened background checks, mandated periodic psyche evals, etc.

Cite your sources please. I have a very significant doubt that this is empirically true.

In fact I'd be willing to wager that the nature of the job provids an improvised filter that achieves the exact opposite effect.

Are you saying cops are on average less scummy? Why is that a conclusion that you find to be inherently true?

Not saying they're bad, most aren't, however, you wanted to be the guy with the power- There is possibly a reason for that.

Sure, but there's nothing that suggests the underlying motivation would be negative. For example, a lot of people cite a desire to protect and serve their communities. Just because there is a motive for something doesn't imply that it's ulterior or nefarious.
