The goals of this guide, which was funded by the national institute of Corrections and National Institute of Justice, are simple but important. It is hoped that the guide will result in improved prevention efforts, planning, and response, so that some emergencies may be averted entirely and others may be mitigated. If this guide helps prevent violence in just a few locations and if it minimizes injuries, deaths, or escapes during just a few prison crises, then it will have fully satisfied its objectives.
