If I had been part of the group of men and women who plotted the assassination of John F. Kennedy-- if there was a plot-- I would very gratified to know the state of the conspiracy theories today: it's a colossal mess.
It's democracy in action, of course, but a mess. A simply search of Youtube will turn up dozens and dozens and dozens-- if not hundreds-- of amateur criminologists all claiming to have turned up some hitherto secret detail that would finally prove that there was a conspiracy. And nothing, of course, does more to discredit the idea of a conspiracy than a multitude of crackpot theories.
Obviously, a number of crackpot theories does not really diminish the possibility that there was a conspiracy. If anything, these crackpot theories are the result of the massive gaps and omissions and errors in the initial investigation and the Warren Commission's report on the assassination.
So when some theorist announces that he has proven decisively that there was no conspiracy, he is missing the point. He can't prove that there was no conspiracy. He can't even prove that Oswald fired the shots. He can only provide answers to the questions that a conspirator would be happy to offer as evidence.
That's why there is such an obsession with proving that Kennedy was shot from behind. Zing, bang, biff: no conspiracy. But of course, even if the proof is decisive (it's pretty good), it only proves that the shots came from behind.
When Dale Myers insists that he has proven conclusively that the shots came from the 6th floor of the Texas Book Depository, I really begin to wonder if he isn't in the pay of the conspirators. The idea that he can establish, from his CGI reconstruction, that the shots came from exactly that location-- that he can insist that he didn't set out to prove that they came from this location to begin with and that he only "discovered" it from his "research"-- beggars belief. Is he serious? Why would he make such a ridiculous assertion? Why not stick to something reasonably credible and demonstrable, like the idea that the shots probably came from behind and above? Because he has an agenda.
And PBS' Nova later showed that a more accurate reconstruction of the assassination implied that the shots came from the Dal-Tex building: at least these researchers accepted the science, not the ideology, while acknowledging that identifying the exact location of the shooters is not really possible.
ABC News, in their report, insists that the FBI has established that the bullets could only have come from the gun owned by Oswald. We now know just how reliable that evidence is: the FBI itself has informed other law enforcement forces that it will no longer provide testimony to that effect in any court case in the U.S.
ABC News insists that a palm print from Oswald's hand was found on the barrel of the rifle. It omitted the fact that no prints at all were found when the rifle was initially examined by the most credible expert: the FBI's Sebastian Latona. He reported that no identifiable prints could be found anywhere on the rifle. It was returned to Dallas where the Dallas police, surprisingly, found the magical palm print. ABC News also reported that Oswald's finger prints were found on the boxes used to form the "sniper's nest". But only one was recent, and Oswald's job, after all, was to handle boxes on the 6th floor. No other boxes were tested. Other prints from other Depository employees were also found. And so were prints from the police-- the evidence was contaminated and would never have been accepted in court.
If Oswald had lived to receive a fair trial and he had had good representation, I think it is quite likely he could have given the Dallas prosecutors a hell of a run for the money. He would have been convicted anyway, because juries can be easily swayed by the weight of opinion held by what they perceive to be the establishment, but a reasonable person might easily have concluded that nobody showed that Oswald actually fired the shots, or that they could not just as well have originated from the Dal-tex building, or that Oswald was not exactly what he said he was: the patsy in a conspiracy.
Many Warren Commission defenders love to point out that it's been 50 years now and no conspirators have yet come forward to confess their role in the assassination. And if one did, would that change their minds? They would never believe him.
