Jack Maple

Jack Maple began his career as a New York City Transit Police officer before becoming the first person to hold the newly created position of deputy police commissioner for operations and crime control strategies within the New York City Police Department under Commissioner William Bratton. Maple developed CompStat, a crime-fighting management strategy built around frequent meetings that compared up-to-date, precinct-level crime statistics against maps of recent incidents so that police commanders could be held accountable for identifying emerging patterns and directing resources to them quickly. The approach, credited with contributing to sharp declines in reported crime in New York City during the 1990s, was subsequently adopted by police departments across the United States and internationally. Maple co-authored the book The Crime Fighter describing his methods, and his career later inspired the television series The District.
