New Fourth Edition of the acclaimed and foundational study of police culture and practice, political accountability, application of and obedience to the rule of law in stops and arrests, and the dilemma of law versus order in free societies -- by the renowned sociologist Jerome Skolnick using innovative and influential research techniques in law and criminology. A respected scholar of the early law and society movement, Skolnick interviewed police and criminals, rode extensively with detectives and attended interrogations, and ultimately saw police conduct and mentality from the inside, before such methodology became popular. Every student of law and society knows this book, and it is available again with a new Foreword by Candace McCoy and a new Preface by the author. Fifty years after his innovative research began, the continuity and change of policing and law is seen again, in all its richness and nuance.
