An excellent addition to professinal literature not only for police but also for corrections and social rehabilitation personnel. It fills an existing need for a text which will assist workers in the helping professions to respond appropriately to deviant and disturbed behavior in their encounters with the public and enable them to function optimally as an ally of medical and paramedical therapeutic professionals. The authors, eminently qualified by training plus years of psychological, psychiatric, clinical, and teaching experience have produced an outstanding text.
