Having to cast doubt on the evidence as the product of lies or fakery is an implicit acknowledgement on Stone's part that the evidence links Oswald to the crime.
The same could be said for the naysayers who frequent this forum. Yet they would never admit that the Warren Commission got anything right.
They reject any and every claim by the WC regardless of its significance to the event. It can say nothing about Oswald's guilt, be completely irrelevant to that question, but it has to be denied. Why? Because it's part of the "official story".
"Official story." They argue a tautology: the WC is supposedly the "official story" and so must be rejected because, well, it's the "official story." I have no idea what "official story" means since it was never approved by any element of the government and thus never made "official." In fact, the government authorized several follow up investigations, e.g., the Rockefeller Commission, the HSCA. So much for being the "official story."
