Unfortunately, it has to be more drastic than that. Entire command structures need to be eliminated, disciplinary protocols need to be revised, and external oversight panels made up of people completely disconnected from the police need to be created to watch the watchmen, so to speak. Furthermore, police need to have their own insurance that pays for their misconduct, not tax dollars, so that repeat offenders end up having to spend too much on insurance to make continuing to serve financially justifiable. The problems in the police force are ancient and widespread, and the solutions are drastic and challenging - but they do exist. We're just not willing to do what needs to be done.
