John,
Great post.
I think the literature is particularly damning. I wonder if those publications were ever checked for Oswald's fingerprints?
My current (lol) theory is a synthesis of Ion Pacepa's Programmed To Kill and Gus Russo's Live By The Sword, with a little reverse spin on John Newman's Oswald and the CIA thrown in.

PS The only problem I have is Buell Wesley Frazier's saying the package was only 24-to-25 inches long, and that Oswald carried it with one end cupped in his hand, and the other end in his armpit.
Hi Thomas, thanks for the feedback. As for Frazier;
1. Frazier tells us during his testimony that he wasn't "paying much attention to the bag"
2. Oswald tells Frazier he's carrying curtain rods
3. Oswald tells his interrogators that he has his lunch in the bag.
4. Frazier says the bag was on the back seat.
5. Oswald says he carried the bag on his lap.
6. The bag matches the size of the broken down rifle.
7. The bag has Oswald's prints.
8. The bag was found in the sniper's nest.
