The assassination of John Fitzgerald Kennedy is one of the milestones of history. Everyone, it is said, remembers where they were when they heard the news. Because the official investigation, the Warren Commission, set up by Kennedy's successor in the White House, Lyndon Johnson, was such a whitewashing travesty of justice, the world has felt itself free to speculate ever more wildly about what really happened in Dealey Plaza, Dallas, in November 1963.The killer, said the Warren Commission, was the peculiar loner, Lee Harvey Oswald, and he acted alone. Evidence, science and common sense have long ago proved that this was not possible. So it was the Russians. It was the Cubans. It was the Mafia. It was Lyndon Johnson. It was the Secret Service. It was the FBI. It was the CIA. It was that murky conspiratorial bunch, the Military-Industrial Complex.This book evaluates all the above and comes to another conclusion entirely. The reason that we are still arguing about who was responsible for a murder committed in front of a large crowd in broad daylight is that no one was prepared to put up their hands and admit their responsibility for not doing their jobs properly. Yes, there was a conspiracy, but the 'cock-up' element was even greater. Why was there inadequate Secret Service protection for the president in Dallas? Why was the motorcade route made public well in advance? Why was Lee Oswald identified on the word of a single witness? Why was Jack Ruby allowed to slip past dozens of policemen to kill Oswald? Why were the lawyers of the Warren Commission allowed to select witnesses and bully them into saying what they had not seen? Why did subsequent governmental inquiries fudge the physics of a headshot and a bungled autopsy? Why does the American mainstream media still cling to the lone gunman, single bullet theory?The answer is simple. Everybody in 1963 and for many years afterwards were far too concerned about covering their own backs. Truth and justice got lost somewhere in all of that.
