Jack Maple

More cities hired Maple and Linder as consultants, including Newark, New Jersey, Baltimore, Maryland, and Istanbul, Turkey. In 1999, Maple co-wrote a book, The Crime Fighter: Putting the Bad Guys Out of Business, published by Doubleday. Maple also began to co-write the prototype for the weekly television series The District.

Maple implemented COMPSTAT in New Orleans. In 1996, crime statistics in New Orleans went down 22 percent in nine months and kept going down for four and half years. In late 1997, Ed Bradley returned to New Orleans for another 60 Minutes special. He did a glowing report, reporting that with COMPSTAT in New Orleans, it is becoming one of the safest cities in America.

Maple was known as a sharp dresser. He would be seen walking around the city wearing a Homburg hat, polished wing tipped shoes with spats, and a tailored three piece suit with a bow tie. He was photographed by photographer Helmut Newton in 1996 in a session to Vanity Fair.

Bill Bratton, head of the New York transit police department while Maple worked as a lieutenant, noticed that Maple's way of crime fighting showed a dramatic decrease in robberies. When Bratton was promoted to police commissioner in 1994, he took Maple with him as Deputy Police Commissioner to One Police Plaza. Maple called his strategy computer analysis of computer statistics—COMPSTAT.

The 11 April 1983 issue of New York Magazine contains an article on Maple, called "The Cop Who Loved the Oak Bar"; the article was written by Michael Daly, and appears on pages 34–37.

Jack Maple (September 23, 1952 – August 4, 2001) was a New York City deputy police commissioner for crime control strategies. He created the CompStat methodology of crime fighting and law enforcement strategy. He coauthored the book The Crime Fighter, and inspired the television series The District.

John Edward Maple was born in 1952 and grew up in Richmond Hill, New York on the corner of Forest Park at 108th Street and Park Lane South.

Maple became a transit police officer, during a time when the position was considered one of the most dangerous jobs in New York. Maple rose from an undercover detective patrolling Times Square and the 42nd Street station at Eighth Avenue to the rank of Lieutenant in the New York City Transit Police.

During this time, Maple was diagnosed with colon cancer. He still had a sense of humor, dismissing it as a bump in the road. The cancer progressed very rapidly though. Maple said that he wanted his funeral in the late afternoon, and he wanted the procession to go up 42nd Street, past Grand Central Terminal right around rush hour. He knew it would tie up traffic, saying "For once they could wait for the fat cop". At Maple's funeral, Mayor Giuliani hailed him as a great innovator in law enforcement who helped make New York City the safest large city in the U.S.
