Dan Emmett was just eight years old when President John F. Kennedy was assassinated. The events surrounding the president's death shaped the course of young Emmett's life as he set a goal of becoming a US Secret Service agent-one of a special group of people willing to trade their lives for that of the president, if necessary. Within Arm's Length narrates the story of Emmett's journey in this coveted job-from the application process to his retirement as assistant to the special agent in charge on the elite Presidential Protective Division (PPD). Here he discusses some of his more high-profile assignments in his twenty-one years of service, including the PPD and the Counter Assault Team where he provided arm's length protection worldwide for Presidents George Herbert Walker Bush, William Jefferson Clinton, and George W. Bush. This memoir describes the professional challenges faced by Secret Service agents as well as the physical and emotional toll that can be inflicted on both agents and their families. Within Arm's Length also shares firsthand details about the duties and challenges of conducting presidential advances, dealing with the media, driving the president in a bullet-proof limousine, running alongside him through the streets of Washington, and flying with him on Air Force One. With fascinating anecdotes, Emmett weaves keen insight into the unique culture and history of the Secret Service.
