Unfortunately police abuse will never go away due to the main reason of the "Code of Silence". There was a study done by "The National Institute of Justice" that reported that about
one-quarter (24.9 percent) of cops agreed or strongly agreed that whistle blowing is not worth it, more than two-thirds (67.4 percent) reported that police officers who report incidents of misconduct are likely to be given a “cold shoulder” by fellow officers, and a majority (52.4 percent) agreed or strongly agreed that it is not unusual for police officers to “turn a blind eye” to other officers’ improper conduct. A surprising 6 in 10 (61 percent) indicated that police officers do not always report even serious criminal violations that involve the abuse of authority by fellow officers. Combine that with bigot cops and the problem becomes even more serious. The only way to curtail this discrepancy is to have a 3rd party or out sourced entity that will hold cops accountable instead of the "Internal Affairs" division which encompasses corruption, integrity issues and lapse in accountability.
