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

This is Zapruder frame 292 where we can first see Mary Moorman engaged in photographing Kennedy. You can see that he hasn't reached her yet, and she is turned towards him, to her right. She's holding the camera in position to shoot, so she could have snapped the shutter right here. But, we are expected to believe that she didn't, that she waited for him to pass her, to be on the other side of her, and get to where it was the back of his head that she was seeing, and then she clicked. Why would she do that? Why would she wait? Why didn't she click the shutter right here at Z-292 or soon thereafter?
