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

Talk about density, there is no rock or block of wood in the world that can compete with Unger and Hondo.

The relevance of this image is that a) it involved Mary Moorman capturing a motorcycle policeman on Elm Street similar to how she captured BJ Martin except that in this case he was photographed slightly before he reached her, and b) it shows his arm to be straight and diagonal, and it does not show his forearm to be horizontal. The same was true of Martin.

So, even though this picture was taken before he reached her, it demonstrates that Mary could not possibly have captured his right arm alone- even if he had progressed to Martin's position, vis-a-vis Mary.

It is the closest comparison we have to the photo she presumably took of Martin. That makes it relevant.
