The Chicago Police Department in August 1968 initiated a " police riot " according to the Walker Report which gathered testimony on the violence surrounding the 1968 Democratic National Convention and Anti-Vietnam War protests . Years later , the Chicago Police Department would deal with even more scandal involving the now infamous crooked cop Lt. Jon Burge and the torture cases that came out of his district . The New York Police Department ( NYPD ) had a prominent case of two detectives working for the Mafia during the 1980s . The Los Angeles Police Department ( LAPD ) in the late 1990s had a large incident of misconduct with the Rampart scandal implicating 70 officers of an anti-gang unit called C.R.A.S.H. . This resulted $ 125-million in lawsuit settlement payouts , dissolving of the unit and the LAPD entering into a consent decree with the U.S. Department of Justice on comprehensive reforms
