'Killing another human being is beyond description. Each time it's like killing a little bit of yourself.' James R. Jarrett survived a violent upbringing, and later the war in Vietnam. Survival is now his business. He runs the Phoenix Firearms Training Centre in Arizona. The courses Jarrett offers prepare his clients to meet their own worst fears - in mock ambushes, muggings and raids. And there's a philosophy to go with the training: 'Survival requires no apology'. Jarrett has come to believe there is a stark choice between trust and survival. He has made his choice, and has adopted a personal creed to match: 'I do believe in God, but I really don't think he gives a damn about us'.
