Crime policy ought to be guided by science rather than ideology, argue Hugh Barlow and Scott Decker in this incisive and original collection of essays. Establishing the value and importance of linking theory and practice, the contributors to Criminology and Public Policy provide a comprehensive treatment of the major theories in criminology and their implications for criminal justice, crime control, and the larger realm of justice. In applying theories to real world issues-such as reducing crime and violence, prisoner reentry policies, gang behavior, and treatment courts-the contributors take both a macro and micro level approach. They find, too, that it is often difficult to turn theory into practice. Still, the very attempt pushes the criminal justice system toward workable solutions rather than ideological approaches, an orientation the editors believe will lead to greater progress in combating one of our society's greatest difficulties.
