I did read "Best Evidence" many years ago. I don't find it credible.
Wow, now there's a surprise....
You find nothing credible that points away from the official narrative.
But now that you have already confirmed that you don't find Lifton's evidence credible, there isn't much point in answering your question. It'll be a complete waste of time, just like talking to you is most of the time.
Great. I read the Warren Commission Report years ago, and I don’t find it credible. How does that answer the questions posed to you? Now where’s your evidence placing Oswald on the sixth floor at the time of the shooting?
Why do you get to demand answers when you provide none of your own? If Duncan banned such people, you’d be the first to go.
He said he had answered our questions by telling us to read the Warren report. Like you, I also did that, years ago and recently I had another look at Chapter 4 (which deals with the assassin on the 6th floor) and there isn't any kind of explanation or even a shred of evidence in there to support Richard's claims that Oswald was on the 6th floor when the shots were fired and/or that he did come down the stairs unnoticed within 75 seconds after the last shot.
