Internal investigations are also BS. If police officers are officers of the court, judges should have the authority (and use the authority) to strip the officer of the authority to act as an officer. Much like contempt of court, it should not require formal hearings or process to immediately remove bad officers from duty. At that point the police department would effectively have an ordinary citizen on their payroll, unable to wear a uniform or make arrests or risk being charged with impersonating an officer and kidnapping.
