It is interesting that Howard Rosenberg points to the "Nova" documentary as the sane alternative to my film "JFK" in his Feb. 7 column ("A Ratings Conspiracy"), but, in praising it as "meticulously fair," he ignores the ridiculous premise of the "Nova" film.
Take, for example, the "Nova" re-creation of the fatal head shot to President Kennedy: Placing a loose skull atop a platform, they shoot it from above and behind at a point where the skull and platform meet. Fragments flew all over but the largest piece flew up and back. This supposedly proves that the shot came from the Book Depository. What they don't mention is that a flesh-and-blood head attached to a body in a moving vehicle reacts nothing like a skull casually placed on a podium. A nice demonstration, but it proves nothing.
Equally preposterous is the program's claim that Oswald got off three shots in under six seconds, an endorsement of the magic bullet theory. Had the program's producers researched the actual "science" of this improbable feat (by, say, reading Josiah Thompson's "Six Seconds in Dallas," an excellent exploration of the marksmanship required to accomplish this), they might not have championed this approach with blind enthusiasm.
