This book was scheduled to be sent to the printer the same day the World Trade Center was blown up in 2001. Interest in school shooters took a back seat to interest in terrorists attempting to destroy our country. I put this manuscript on the shelf, believing that would be its final resting place.Through the years since then, there have been schoolyard shootings and other shootings in workplaces, and among relationships, but I had gone on to write of other things. However, the most recent shooting at Chardon High School in Chardon, Ohio, by a seventeen year old boy, who cold-blooded shot and killed three students, moved me to such extreme sadness that I searched for and found this manuscript, dusted off the cover and started reading. I saw that I was thinking the same things today as when I wrote this book, and realized once again there are some important conclusions here that may help us understand the almost exclusively male impulse for boys and men to shoot others when they are in the throes of their overwhelming frustrations.A mother sending her child to school, or a woman who has left her boyfriend or husband, or a person in a workplace who may be the target of a frustrated fellow worker, all share the fear and uncertainty of possible danger from readily available guns in the hands of men overtaken by their personal torment.This book is a gathering of information about these three kinds of killings to learn why they are almost exclusively male. Not all males are killers to be sure, but almost all killers are male. Efforts to understand this phenomenon may lead to reducing the stress which surrounds some males, and which propels alienated males to murder.As a psychologist and a school administrator who worked with troubled juveniles, and an author of several sociological research books including Male Crime in America, and Childhood Roots of Tyranny, I have written this book to present the case once again for reducing male violence. We must keep trying. Testosterone is no excuse for murder.-- June Stephenson, Ph.D.
