Lattimer's "work" has no credibility.
I was speaking of the FBI's role in the COVERUP. While it certainly did its best to keep its role wrt Oswald covered up I did NOT claim it was involved in the actual killing. Certainly it was determined to keep the information it had indicating a plot was afoot from coming to the attention of the WC and thus did not tell it about the threats against Kennedy it had uncovered prior to the assassination. Hoover's hatred of the Kennedy's and love of LBJ played a role in the entire affair and he believed JFK got what was coming to him.
Marina has changed her opinion about what happened and has rejected most of what she was saying.
No one that I know of has claimed that ALL MCs were incapable of the shooting just that Oswald's was. That was made certain since it could not have been used IN THE CONDITION IT WAS FOUND to do so. (Hopefully you won't ignore what is actually claimed in order to set up further straw men.) However, better shots than I have claimed it to have been virtually impossible and I have seen no evidence proving them to be incorrect. WCR testimony shows beyond a shadow of a doubt that Oswald's rifle could have only hit anything through sheer luck.
Robert Oswald's book is just about as convincing as most of the books which ignore evidence to the contrary and claim LHO did it.
I could answer all those questions and more had I the resources devoted to finding the facts that the WC had to concoct its Report. Not all the Commission even believed its lies in any case. Richard Russel, Russel Long and Wade Boggs did not buy them. And I believe John Cooper had doubts as well. Most of it was convinced that the truth (which they feared was a communist conspiracy to kill JFK) would lead to a world war. As things stand I can only say that the flaws within the theory of the Lone Assassin simply make it unbelievable unless you want to believe it.
Latimer's work has no credibility? So you have read his book? No of course not. Now that's knocking down a straw man.
Marina may have changed her mind about a conspiracy. She has never recanted her testimony. That she took the pictures of Oswald with the rifle. That he owned that rifle. That he took a shot at Walker. Etc. She has never stated she was told to lie or make things up.
Other than the discredited audio tape The House Committee found no other evidence of a conspiracy and stated Oswald still shot the President and the policeman.
I see, any book that doesn't support a conspiracy is de facto worthless. Robert Oswald knows more about LHO than you or I will ever know. It would take a lot of evidence for someone in my family to believe I would ever committ a crime. Talk about a closed mind.
The problem with all those conspiracy people you mention is they all have a totally different theory as to who did it. That sounds more like people wanting to make money by selling a book. There are tons of resources for you to check. You can find the WC report online I beleive. My acceptance of LHO assassinating JFK is based on facts. As I stated before if Oswald ever went to trial he would have been convicted of both the JFK and the policeman murders.
