This book addresses police threat assessment of, vulnerability assessment to, and defense against weapons of mass destruction. The text explores the distinctions between military and police operations and includes an examination of the U.S. counterterrorist policy, assessment of the various weapons of mass destruction and the terrorist ability to make and use them, the legal limitations of police response operations, and the defensive response to this form of attack. Relying on both experience and research, the author has synthesized the varied military, law enforcement, and private security approaches into a detailed analysis of the threat posed by terrorist use of vehicular bombs and the necessary internal response. With the firsthand experience of applying the knowledge in an actual threat environment, the combination of historical perspective and reality confrontation produces a most effective examination of the subject for the police administrator and emergency planner. The text will also be practical and useful for governmental administrators, military police, and private security personnel.
