In what is a relatively short historical time frame the police began to reconsider their fundamental mission, the nature of the core strategies of policing, and the character of their relationships with the communities that they serve. This volume brings together leading police scholars to examine eight major innovations which emerged during this period. Including advocates and critics of the innovations, this comprehensive book assesses the impacts of police innovation on crime and public safety.
