Tragic Truth will change understanding of the most important murder in our history: Lee Oswald's shooting of President Kennedy. It is now settled fact that Oswald did it, alone; no conspiracy, only one strange man firing three bullets. Still unanswered and troubling is the question "Why did Oswald kill Kennedy?" Excellent books including the Warren Report, Case Closed and Reclaiming History failed to define a motive. Why? Because it's the wrong question. Oswald revered JFK and had no intent to harm him. But he thought he had reason to take revenge against former Secretary of the Navy and now Governor of Texas John Connally, riding with Kennedy. He nearly killed Connally and accidentally murdered our President. James Reston, Jr.'s The Accidental Victim set the table; this is the full meal. After 50 years of research, 774 pages present and validate all important facts with hundreds of photos, maps, diagrams and documents, supported by 3481 source notes. The book displays direct evidence that Oswald wrote in his pocket notebook "I will kill John Connally." Open minds will conclude, beyond any reasonable doubt, that inept Lee Harvey Oswald killed an innocent victim by accident, and changed history. That is the Tragic Truth.
