"This volume is a must-have book for anyone who cares about preventing crime and avoiding harmful programs. The book offers McCord's classic evidence that good intentions can produce disastrous results, and that crime prevention should be evaluated no less rigorously than a new and powerful drug." Lawrence Sherman, Director, Jerry Lee Center for Criminology, University of Pennsylvania "[McCord] clearly was a researcher of unbounded energy whose life's work has added greatly to the corpus of criminological knowledge. This book is an excellent collection of that work. The methodology of her research in the developmental study of crime is both classically rigorous and strikingly inventive." The Law and Politics Book Review "The essays are mostly based on topics close to Joan's heart...The book closes with a truly inspiring autobiography and a list of all of her publications."
