Now, here's something interesting. Robin Unger says that the Muchmore frame that I picked that corresponds with Moorman is Muchmore38, which is 4 frames before the fatal head shot.
Well, I wasn't thinking about it at the time, but the Zapruder frame that I concluded must correspond to the Moorman photo is Z-309. And that too is 4 frames before the fatal head shot.
I love it when everything works out.
Alan Murphy Logic dictates that Oswald dd not write this letter. But it winds up being more ammo for the bad guy Warren Club defenders to characterize him as the lone nut. I don't know why something like this was put together. There was a motive but we will never know what it was.
