Lee Harvey Oswald was lone assassin - official?

Another 13,000 John F Kennedy assassination plot papers are released and still there is no juicy morsel for the conspiracy theorists that it was all a giant conspiracy involving the KGB/Mafia/trade union honchos/rednecks. No one, according to the latest released files, was pulling the strings for Lee Harvey Oswald. He was a nutter pure and simple and didn't have some KGB baddie guidng him or some Mafia boss supplying the weapon. There is nothing in the files to suggest that other people were or even must have been involved. We know pretty much everything about the assassination of John Kennedy in 1963 but of course not all the files have been released. Three per cent of the five million or so logs relating to that devastating moment in US history remain classified. So I guess there could be something in the three per cent which might change the whole perspective of the assassination and point to others who conspired with Oswald but it seems unlikely. If there was definite, totally credible evidence that Moscow in some form was behind the assassination, then surely in the near-60 years since those shots were fired, it would have trickled out by now. But but but it did somehow always seem extraordinary that one miserable little man took it upon himself to shoot dead a president who had given new hope to the US and to most of the western world of a new era of great American leadership. A conspiracy seems so much more realisic. But I'm not and never have been a conspiracy theorists. I DO believe that American astronauts landed on the moon, and that the Pentagon was hit by one of the highjacked airliners in 2001. But until 100 per cent of the five million files on JFK's assassination are released I will hold a tiny bit of doubt about Oswald being a lone, unsupported, gunman.
