"Delinquency in a Birth Cohort is a turning point in criminological research in the United States," writes Norval Morris in his foreword. "What has been completely lacking until this book is an analysis of delinquency in a substantial cohort of youths, the cohort being defined other than by their contact with any part of the criminal justice system."

This study of a birth cohort was not originally meant to be etiological or predictive. Yet the data bearing on this cohort of nearly ten thousand boys born in 1945 and living in Philadelphia gave rise to a model for prediction of delinquency, and thus to the possibility for more efficient planning of programs for intervention. It is expert research yielding significant applications and, though largely statistical, the analysis is accessible to readers without mathematical training.

"No serious scholar of the methods of preventing and treating juvenile delinquency can properly ignore this book."—LeRoy L. Lamborn, Law Library Journal

"The magnitude of [this] study is awesome. . . . It should be a useful guide for anyone interested in the intricacies of cohort analysis."—Gary F. Jensen, American Journal of Sociology

"A book the student of juvenile delinquency will find invaluable."—Criminologist

In the early 1980s the radical group MOVE settled into a rowhouse in a predominantly African-American neighborhood of west Philadelphia, beginning years of confrontations with neighbors and police over its anti-establishment ways and militant stance against all social and political institutions. On May 13, 1985, following a period of increased MOVE activity and threats by neighbors to take matters into their own hands, the city moved from bureaucratic involvement to violent intervention. Police bullhorned arrest warrants, hosed down the rowhouse, sprayed tear gas through its walls, and dropped explosives from a helicopter. By the end of the day, eleven MOVE members were dead, an entire block of the neighborhood was destroyed, and Mayor Wilson Goode was calling for an investigation.

How did this struggle between the city and MOVE go from memos and meetings to tear gas and bombs? And how does the mandate to defend public order become a destructive force? Sifting through the hearings that followed the deadly encounter, Robin Wagner-Pacifici reconstructs the conflict between MOVE and the city of Philadelphia. Against this richly nuanced account, in which the participants—from the mayor and the police officers to members of MOVE and their neighbors—offer opposing versions of their aims, assumptions, and strategies, Wagner-Pacifici develops a compelling analysis of the relation between definition and action, between language and violence.

Was MOVE simply a radical, black separatist group with an alternative way of life? Or was it a terrorist cult that held a neighborhood and politicians hostage to its offensive language and bizarre behavior? Wagner-Pacifici shows how competing definitions of MOVE led to different strategies for managing the conflict. In light of the shockingly similar, and even more deadly, 1993 Branch Davidian disaster in Waco, Texas, such an analysis becomes imperative. Indeed, for those who hope to understand—and, finally, to forestall—the moment when language and violence are inexorably drawn together, this book demands attention.
