Here's a piece of irony. Look who was standing behind Oswald when he got shot: Police Inspector J. H. Sawyer.
He's the same cop Oswald was talking to in the doorway as he was leaving the TSBD. But, Sawyer never mentioned their little chat.
And if you disagree with me about that being Oswald in that Three Tramps photo, then you tell me who that is talking to Sawyer. It's only been 52 years. Isn't that long enough to find out? I say he's Oswald.
