Robin Unger is getting all excited because the DPD letter described Oswald as standing "on the sidewalk" intead of "in the doorway."
Unger, it was just an offhand remark by the officer who wrote the letter. We know what he was referring to, and it had to be the figure in the Altgens photo. So, whether he knew it or not, he was talking about the doorway even though he said the sidewalk.
Jesus Christ, you are juvenile, Unger. Grow up!
