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

Unger says that "B" (the left side of Martin) was not in the way of seeing "C" (his right arm) because "A's" view (Mary Moorman) was "over the top of 'B' (his left side).

That is ridiculous, Robin because Mary Moorman was only 5 feet tall and standing on the grass. Her view wasn't on top of anyone. Furthermore, her angle of view was such that she didn't have to do anything with her camera except point it. 

   
You are a phony, Robin. For once in your life, why don't you get an actual camera out and prove what you claim with photos that you take. I'm not worried if you do. The Laws of Optics work exactly the same in Australia as they do in Dallas, Texas. You can't be on someone's left side and photograph him and capture only his right arm. It's impossible!
