Foreword by Massad Ayoob. This book is the preeminent study of the 1970 Newhall shooting, in which four California Highway Patrolmen were slain. A watershed event, the massacre spurred radical changes in law enforcement training and procedures throughout the nation. This book offers the most critical, in depth analysis of the shooting to date, and explores the "lessons learned" from this event. It challenges the notion that these lessons have been fully incorporated into American law enforcement training, and examines ways in which modern law enforcement and self-defense training can be improved so that the sacrifices of these valiant officers were not in vain.
