About the Crimefighters

The CrimeFighters, over their careers as Police Chiefs, sworn officers, researchers, consultants and devotees of civic life have cut homicide and other violent crime by half in “the murder capital of America.”

The CrimeFighters LLC gives dedicated and expanded focus to the crime reduction services Linder has provided to law enforcement agencies for over ten years. Joining The CrimeFighters as principals are three of the nation's most renowned and effective law enforcement professionals, who each were the operational directors, under their police CEOs, of nation-leading crime reductions among cities of their own size over multiple years.

The CrimeFighters have made major inroads on "quality of life" crime and the urban blight that comes with it. They have improved crimefighting efficiencies and reduced overall complaints by citizenry in numerous metropolitan areas nationally.

The CrimeFighters is the only crime consultantcy who can be held directly responsible for the improved effectiveness of over eight major American Police Departments.


Founders Jack Maple and John Linder contributed a unique combination of expertise to this enterprise. Under the direction of New York Police Commissioner William J. Bratton, Maple created the COMSTAT process that has been credited by the John Jay College of Criminal Justice in its study of the sustained, dramatic drops in crime in New York City with being “perhaps the most significant aspect of the [New York Police] Department’s organizational changes within the last few years”.
