Dirty Thirty (NYPD)
The Dirty Thirty was a police corruption conspiracy that took place between 1992 and 1995 in the New York City Police Department's 30th Precinct, serving Harlem, and resulted in the largest collection of police officers charged with corruption in New York City in almost a decade. A group of rogue officers, led by Sergeant Kevin P. Nannery, participated in various unlawful activities, including civil rights conspiracy, perjury, extortion, grand larceny and the possession and distribution of narcotics.
