Is the Zapruder Film a bigger hoax than global warming?

The House Select Committee on Assassinations described the Zapruder film as "the best available photographic evidence of the number and timing of the shots that struck the occupants of the Presidential limousine." The Assassination Records Review Board said it "is perhaps the single most important assassination record." The film was originally touted by the vast majority of conspiracy theorists as incontrovertible proof of a conspiracy but is now believed by many assassination researchers to be a sophisticated forgery.Among those who believe the Zapruder film has been altered are John Costella, James H. Fetzer, David Lifton, David Mantik, Jack White, Noel Twyman,Tom Rossley and Harrison Livingstone, who has called it "the biggest hoax of the twentieth century."
