At the very least, a federal department to review issues with local police departments is necessary. Right now cops investigate their friends and themselves. It’s global news when one decides to even fire (not even arrest) a friend despite video evidence of a crime. This shouldn’t happen. It should be possible for the public to submit evidence to a federal police review board and let them handle investigations in a less biased manner. When a cop carries out an illegal search or decides to kill someone in a fit of rage as often happens, that should be well out of the domain of local police investigation and should go straight to the federal government.
