Book excerpt: When shots rang out in Dallas on November 22, 1963, U.S. Secret Service Agent Rufus W. Youngblood immediately lunged over the seat of the vice president's car and bravely used his body to shield Vice President Lyndon B. Johnson. Faced with the unknown, Youngblood maintained this protective position as they sped toward Parkland Hospital. Throughout that fateful day, he vigilantly remained by LBJ's side to ensure his safety. This candid memoir includes Youngblood's first-hand account of the Kennedy assassination and its aftermath, as well as highlights from his twenty-year career in the Secret Service during which he protected Presidents Truman, Eisenhower, Kennedy, Johnson, and Nixon. Readers will enjoy Youngblood's behind-the-scenes look at some of the most pivotal events in U.S. history, humorous anecdotes, and descriptions of the complexities, risks, and constant tensions involved in protecting America's chief executive. A unique and comprehensive collection of more than one hundred photographs has been added to illustrate this agent's amazing story.
