That the Zapruder Film Is Authentic Proof that the Zapruder film is authentic One of the central arguments in the book Assassination Science is that the Zapruder film is not authentic.
Various researchers argue that frames had been cut out for some conspiratorial motive.
On pages 310 to 315 Dr. Mantik discusses the strange ghostlike images in the sprocket hole area. He does not know what caused them and suspects that they indicate tampering. To date, no one has correctly explained what those images are and how they were created. For many years I have puzzled over them and discussed them with other researchers, but never reached a firm conclusion due to the very poor quality of the Zapruder film versions we have had. Now MPI has released the original Zapruder film with the sprocket hole areas intact.
