"Whenever anyone says the Warren Report was wrong I always ask them if they have read it. Almost no one has.
Bugliosi's remark can be verified by reading the Warren Report yourself and simply asking critics a few questions about what's in the text. I've yet to meet a conspiracy fan who even knows how the report is structured, much less what's actually in it. What they do is watch videos and listen to the stories spun by professional conspiracy pushers without ever bothering to see if the witness statements in the report blows holes in that nonsense.
I mentioned the detail Bugliosi went into. One point that was made was regarding the FBI investigation. They actually interviewed everyone they could locate who was on the bus with Oswald on the trip from Texas to Mexico City. I was a bit surprised at that.
