It is criminally embarrassing that police are not REQUIRED to actually study ethics and the law in order to get licensed to enforce the laws of their jurisdiction. We require licensing for just about everything else: lawyers, doctors, engineers, surveyors, electricians, nurses, hair dressers, and more. But when handing out the authority to enforce increasing complex laws and the legal authority to murder civilians? Nothing really. Just a few weeks of training for the bullies that peaked in highschool.
