Technical Hurdles Suggest Extensive Z-Film Alteration Highly Unlikely

[David Healy]

Of course it was technically possible back then to do some large-scale alteration of the Z-film; amazing things were being done with film effects back in the teens and 1920s. The problem is, when was there time to do it? The backyard photos were easy to fake, and it was done months before the assassination (judging by the differences in the trees and bushes when compared to the DPD reenactment photos).

plenty of time to do the job Ms. Riddle... perhaps you should read my 1998 article based on the premise: IF the Zapruder film was altered, was the time, manpower, expertise (including matte artist and glass painters), equipment, etc. available in 1963-4. Oh and btw, pass on to your friend Jeffrey, those of us whom spent a good portion of our film and/or television careers IN edit suites, under the aegis of very difficult post production directors whom have impossible time deadlines are simply, miracle workers, plain and simple. The impossible? Conquered every damn day!

Altering the Zapruder film simply or extensively film doesn't amount to a mosquito bite on a gnat's ass.... Two (2) weeks, tops!
