One of the US problems was that police precincts didn't pay enough, causing well educated people to seek employment elsewhere. 

This caused cities and towns to have to accept people they normally wouldn't hire just to fill the minimiument amount or people to cover the area that they police.

This means that the police force is filled with people who don't do the job for money per se, but for the sense of authority, and then they abuse that authority.

I was at a bar one time and I sat with a group of people, a few of whom turned out to be cops, and they were practically begging me to join the force lmao. Me, some rando they knew for like half an hour. Your point is valid, if the American police force were noble to begin with. but I feel that American police really just enforces the prison industrial complex, and that most prisoners simply need effective rehabilitation rather than being exploited for free labor via the loopholes in the 13th amendment.
