"As a 23-year-old from a small town in Washington State, the author was plunged into a chaotic city of brawling servicemen, prostitutes, racial violence, enemy rockets, riots, and death. It was a place that would give him a unique opportunity to see up close a different side of the Vietnam War and its effect on the human condition."

"[Loren] identified 37 of the finest warrior authors, warrior trainers and warrior scholars around, and asked them to tell in their own words what being a warrior meant to them. The contributors came from a diverse mix of fellow warriors, from soldiers, cops and SWAT officers to martial art masters to experts in the fields of workplace violence, theology, and school safety."

Law Enforcement

"Wow! Delivers from start to finish."

"Loren has been a prolific and brilliant wordsmith. And this book may be the pinnacle of his craft."

"While some stories are gruesome, they are told with respect and professionalism."

What distinguishes law enforcement officers from people in other occupations... They confront murderers, rapists, arsonists, child molesters, and kidnappers, and they see the victims moments after the crime, sometimes as it happens....

Many officers say, “It's their eyes," when telling their stories in this book. “They’re cold, dark, and malevolent.”
For some, that perception, that disquieting feeling, has remained years after the contact—and they know why. They had stood in the presence of true evil.

"This book shows cops how to use proven defensive tactics to stay alive and uninjured, including how to disarm attackers, deal with drunk or drugged subjects, protect their guns, fend off multiple attackers and more."

Loren W. Christensen
