SMG-
Thanks for your comments.
To be sure, mere reporters and authors, without incarceration, investigative and subpoena powers, can only say for certain so much. Russo is careful to say what he has learned, and to not go beyond that.
Sure, a reporter can gently ask questions, peruse the public domain.
But it remains that Al Haig, Win Scott and Thomas Mann (and State Dep't staffer Thomas) all thought somebody was behind LHO. I do too. Win Scott papers are a curious lacuna in the public record.
Moreover, it is beyond dispute that forma or government investigations into LHO-Havana connections were suffocated in 1963-4 by LBJ order, and that G2'ers have told Russo (and were filmed in his documentary) that other G2'ers triggered LHO.
Did G-2'ers physically assist LHO on 11.22?
As the SBT-LNT theory does not hold water, I think it is an open question.
