"This book is clearly the urgent call by the contributors, who, using tools of their professions, are trying with deep feeling to contribute something to the prevention of a lethal outcome for humanity. They ask, correctly, whether there is time in which we can reframe our priorities. To do so, the authors lead us through a fascinating but disturbing maze of the phenomena of violence in groups, institutions, and the media."-Israel W. Charny, Executive Director, Institute on the Holocaust and Genocide, Jerusalem , in the Preface to This Book"...a unique blend of outstanding experts from the forensic disciplines. Incorporating cutting edge topics confronted by the law enforcement community, these experts, with their varied backgrounds, have delved into the darkest sides of the human personality."-Lloyd E. Dean, FBI Special Agent (Retired) and Co-Founder, Threat Management Group, Inc., Louisville, Kentucky
