Crusader: The Hell-Raising Police Career of Detective David Durk

When David Durk joined the New York City Police Department in 1963, he found an organization with its own set of rules, where bribery and payoffs were routine and no one wanted to be disturbed. Durk set out to fix the whole mess. For 22 years, until he was forced to retire at age 51, he was a thorn in the side of mayors, police commissioners, commanders, sergeants, and beat cops alike. His crusading led to an investigation into police corruption in the 1970s by the Knapp Commission (credit for which usually goes to Frank Serpico) and more recently, the Mollen Commission.
