Edited by the chief librarian and associate dean at John Jay College of Criminal Justice and professor of criminal justice at City University of New York, Encyclopedia of Law Enforcement provides a thorough overview of law enforcement in the U.S and around the world. According to the introduction, the public's view of policing is significantly influenced by the popular media, which oversimplifies police work; therefore, there is "an urgent need for providing students and the general interested public balanced information on what law enforcement does, with all of its ramifications." The encyclopedia's aim "is to survey the entire field of law enforcement and to be as comprehensive as possible."
