Bobble, I'm inclined to agree that a large part of the problem is that police are trained to see themselves as warriors. Community policing and deescalation need to be emphasized more. That's a failure in leadership and education, but I suspect there is also a deeper societal issue here because ultimately police forces are not purely autonomous institutions, they are instruments that serve power interests.

You seem to be contradicting yourself about what makes it hard to convict cops. Or maybe not, maybe the average jurist really does end up concluding that they're not in a position to second guess the people who are out in the streets. If that is the case then they should never have been chosen as jurists.
