relying on what was considered the “best evidence”, the autopsy report and photos; but that didn’t satisfy Lifton. As Lifton was methodically working through the 26-volume Warren Commission report and exhibits, he stumbled upon what would become the fulcrum of his narrative, the answer he was looking for. He read, according to a report by FBI agents Siebert and O'Neill who attended the autopsy and took notes on everything they observed, that it was "apparent that a tracheotomy had been performed...as well as surgery of the head area, namely, in the top of the skull." Since Lifton knew that there was no surgery to the head in Dallas, this was the fact that intensified and focused his research, leading ultimately to the synthesis of the contradictory Dallas/Bethesda evidence to his conclusion that there was intentional fraud, that is, as Lifton puts it, a “medical forgery” to the body of the President. In connection with his body alteration theory, Lifton hypothesized about when and where the alteration took place. He posits that after John F. Kennedy's assassination, unnamed conspirators on Air Force One removed Kennedy's body from its original bronze casket and placed it in a shipping casket, while en route from Dallas to Washington. Once the presidential plane arrived at Andrews Air Force Base, the shipping casket with the President's body in it was surreptitiously taken by helicopter from the side of the plane that was out of the television camera's view. Kennedy's body was then taken to an unknown location — most likely Walter Reed Army Medical Center — where the body was surgically altered to make it appear that he was shot only from the rear. Among the explicitly stated clear implications of the book are the following: The assassination was an “inside” job with, at minimum, a number of secret service men involved—the ones who controlled the scene and the evidence and Oswald was, as he stated after his arrest, “a patsy." Reception Ed Magnuson of Time described the theory as "bizarre", but wrote that Lifton's work was "meticulously researched". According to Magnuson: "Preposterous? Absolutely. Yet there is virtually no factual claim in Lifton's book that is not supported by the public record or his own interviews, many of them with the lowly hospital and military bystanders whom official probes had overlooked." Thomas Powers gave a critical review of the book in New York magazine stating: "There
