The Great Zapruder Film Hoax by Jim Fetzer Of all the presenters who traveled to Duluth for the Symposium , the one who traveled farthest was Dr. John Costella, a theoretical physicist from Australia. Dr. Costella is something of a newcomer to the area of JFK research but he has made astounding contributions already. One of the more fascinating discoveries Costella has made involves the Stemmons Freeway sign in Dealey Plaza. As it turns out , the lens system on Zapruder's camera was patented by Bell & Howell; its characteristics are well documented. As many are aware , Zapruder's Bell & Howell Director's Series 414PD camera was set on telephoto while he filmed the presidential motorcade. This lens has a characteristic "pincushioning" effect which tends to pull the image frames outward . This pincushioning effect is clearly present in the extant Zapruder film , as it should be . Except there is no pincushioning detected for the Stemmons Freeway sign along Elm Street---and there should be. Costella shows that it is physically impossible for pincushioning to occur in portions of movie frames selectively while other portions are free from the distortion . How could the Stemmons sign have escaped the pincushioning ? The short and undeniable answer is that the Stemmons Freeway sign , as it appears , was inserted into the film after it was processed . The sign should have had the same pincushion distortion as the rest of the frame as well as all the frames before and after the ones in which the sign appears. Recall that the extant film shows JFK smiling and waving to the crowd prior to disappearing behind the sign . When he re-emerges he has his hands up to his throat as he reacts to being shot . Irrefutably , the Stemmons sign obscures the throat shot---a frontal throat shot. Some researchers have theorized that the sign was also struck by a shot from the grassy knoll. ( The sign was not made of metal but was plywood.) Are these the reasons an artificial sign was inserted into the extant film? If so, Costella reasons , the extant film was not merely " altered " ---it was " fabricated ". Fabricated , as in " falsified "---with criminal intent , since obstructing justice was , and still is , a crime. assassinationresearch.com/v3n2/v3n2dellarosa.pdf
