Oswald in the doorway: the blog of the Oswald Innocence Campaign, by Ralph Cinque

After acknowledging that this Zapruder frame was taken a full second before the Moorman photo, he says that some "scientific" studies have shown that for Mary to have taken the Moorman photo, that because of her short height, she would have had to step out into the street to do it. That she denied doing. Then, he acknowledged that although there is a lot of belief that the Zapruder film isn't real, there is also some belief that Mary's isn't. Not as much, but some.
