The assassination of John Kennedy was a world-shattering event. The world was a very different place in 1963 and the idea that the President of the United States could be gunned down in broad daylight was almost unbelievable. In America men and women wept openly in the streets for their dead leader. But events soon began to unpick the original version of events. It turned out that official report was little more than a crude government whitewash designed to hide the real truth. Even American Presidents admitted as much. President Nixon memorably confessed in private that the `Warren Report was the biggest hoax ever perpetuated on the American public. It began to emerge that maybe Lee Harvey Oswald, the original lone nut gunman, may not have acted on his own; others were involved, too. That meant no `lone gunman', but a conspiracy.
