After reading this text, the reader will have a fuller understanding of the nature of domestic terrorism and a clearer understanding of the basics. These basics include a review of the complex history that spans thousands of years, an explanation of definitions, a review of contemporary domestic terrorism, and the examination of intelligence gathering, threat analysis, and emergency responses to terrorismincident management. It is hoped that such knowledge as presented here will enhance the public'’s understanding of domestic terrorism and law enforcement'’s ability to prevent and respond to its acts. It focuses almost exclusively on rightwing domestic terrorism because of its strong presence in the last twenty years and the projection of experts that rightwing terrorism will prevail well into the twentyfirst century. The book is divided into three parts. The first part deals with definitional problems associated with policymaker’'s and law enforcement’'s handling of terrorism, an historical overview of terrorism and terrorist incidents in the global community, and an historical examination of terrorism from below in the United States. Part Two addresses the American Hate Movement and patriotmilitia activities. It also discusses the emergence of special interest extremist and terrorism groups that advocate violence based on an ideology or belief, which may include the desire for political and social change. They include ecological resistance groups, antienvironmental movements, animal rights and antiabortion activists. Part Three focuses on effective criminal intelligencegathering techniques and the implementation of terrorismincident management strategies.
