Frank Serpico, American-Italian soldier, police officer and lecturer

Francesco Vincent "Frank" Serpico is an American retired New York City Police Department detective, best known for whistleblowing on police corruption. In the late 1960s and early 1970s, he was a plainclothes police officer working in Brooklyn, the Bronx and Manhattan to expose vice racketeering. In 1967, he reported credible evidence of widespread police corruption, to no effect. In 1970, he contributed to a front-page story in The New York Times on widespread corruption in the NYPD, which drew national attention to the problem. Mayor John V. Lindsay appointed a five-member panel to investigate accusations of police corruption, which became the Knapp Commission.
