I have this idealised vision of a police force that are more like monks. Their main training is mental, meditation, mindfulness, situational awareness, sensitivity training, de-escalation training. They are also extremely well trained in combat and self defence but almost never use it. When they do they can quickly disarm and subdue violent perps without struggle. They exist just to keep the peace between people. People could grow to trust and respect them in a way that they can't for cops.
It would have to be a lifelong pursuit like a real monk, without much financial incentive. The problem is without trust and respect it wouldn't work since no one would enlist. I'm not sure how you would bootstrap something like that.
