I typed up a transcript of this and posted it on /r/cth once upon a time, but I heard a detailed and very believable story about the CIA's possible involvement, told by the usually silent producer at the end of an episode of Dr Gameshow, just on a weird tangent as he was saying goodbye to the hosts because he was moving to Alaska. The basic overview, iirc, was that his dad was a sharpshooter amongst other interesting skills, and he had a lot of same time, same place overlaps with Oswald, and he was also doing some work with some Cubans?

I might still have it buried in a folder somewhere on my laptop.
