"But for those seeking the truth, the facts are incontrovertible.  They can be tested against credible testimony, documents, and the latest scientific advances.  Chasing shadows on the grassy knoll will never substitute for real history.  Lee Harvey Oswald, driven by his own twisted and impenetrable furies was the only assassi at Dealey Plaza on November 22, 1963.  To say otherwise, in light of the overwhelming evidence, is to absolve a man with blood on his hands, and to mock the President he killed."
