He's led an interesting life and he has written an interesting book called Beat Cop to Top Cop: A Tale of Three Cities (University of Penn Press), which comes out next month.
Beat Cop to Top Cop: A Tale of Three Cities documents Timoney's rise, from his days as a tough street cop in the South Bronx to his role as police chief of Miami. This fast-moving narrative by the man Esquire magazine named "America's Top Cop" offers a blueprint for crime prevention through first-person accounts from the street, detailing how big-city chiefs and their teams can tame even the most unruly cities.
Policy makers and academicians have long embraced the view that the police could do little to affect crime in the long term. John Timoney has devoted his career to dispelling this notion.

"If he had thought of him first, Damon Runyon would have invented John Timoney. A self-made man in the 'Runyonesque' mode, John Timoney recounts his remarkable story in this compelling book. He emerges from these pages as a cop's cop and a chief's chief, with a bit of a poet mixed in."—Ray Kelly, New York City Police Commissioner.
"John Timoney writes like he talks (except, unfortunately for the reader, without his delightful Irish brogue). Beat Cop to Top Cop recounts his brilliant career in an always entertaining and insightful way. True to his Dublin story telling heritage, his tale draws the reader into the always exciting world of policing from the beat to the Commissioner's suite."—Bill Bratton, former Chief of Police, Los Angeles.
"John Timoney is pure cop: tough and blunt, sensitive and caring. Deputy Commissioner in New York City, Commissioner in Philadelphia, and Chief in Miami, Timoney helped create Compstat and reduce crime in New York, bring homicide under control in Philadelphia, and demonstrated in Miami that he could reduce police shootings without endangering officers or allowing crime to increase."—George L. Kelling, author of Fixing Broken Windows: Restoring Order And Reducing Crime In Our Communities.
