Civil gang injunctions have become a growing feature of crime control programs in several states across the nation. This volume examines the effectiveness of this strategy and explores the accompanying constitutional controversies related to freedom of speech, assembly, and other rights. The book discusses the costs of gang violence to society and describes the factors that make a given injunction or abatement more or less effective. It also explores the legal and policy issues that stand in the way of gang injunctions and abatement. Providing step-by-step instructions on how to establish a successful injunction and abatement program, the book presents comprehensive research on the theoretical basis for the strategy.
