It’s much cheaper (and better for psychological conditioning to the Policed States of America) to just hire the cheapest community college dropouts with a pant size bigger than their IQ than it is to attract, train, and maintain a respectable (read: “for the community”) police force. If the US adopted similar requirements for their police as a country like Germany, I’d imagine we’d lose well over half of our force instantly, with most of the rest quitting soon after being asked to not shoot people at the first sign of noncompliance.
