When I was 14, a young Marine taught me how to shoot a rifle. My instructor and surrogate big brother went on to enter US history books as the ""Texas Tower Sniper"" after he massacred 16 innocent victims. He was the first recorded mass murderer in American history. Four years later, I was conducting CIA assassination missions as a military sniper in Vietnam. After returning to the US, I spent the next 31 years on the US-Mexican border as a federal agent, where the struggle against the smugglers of drugs and starving human beings has been as harrowing as anything I encountered in Vietnam. The Reaper's Line is a non-fiction account of unparalleled official corruption, national fraud, mass murders, gunfights, desperate sojourners, treason, betrayal, and government wrongdoing. It is a story of smoking six-shooters and blazing machine guns in today's Wild West.
