You would be mistaken. The Warren Commission didn't request the documents be sealed. It was instead a pre-existing governmental rule.
"That one hour movie of Lee Harvey Oswald spouting about his "Fair Play for Cuba" organization"
There was no movie. There was a radio program Oswald was asked to be on after he got arrested. There's nothing coincidental about it.
BTW, the person that shot the films of Oswald at the radio station and in the streets of New Orleans, used to be a Freeper. I knew him. He never wanted to reveal that, but I tell you now because he died a while back.
I have some experience with the world of government agents and he acts, sounds and writes like somebody playing a part for one of our "three letter" agencies.
The term of art is "burning" an agent when they use one in some activity that gets him or her killed or captured. I think that Oswald was burned.
I don't really think that there's anything there in the remaining JFK papers: that was before computers and much magnetic media. All you had to do was find the papers and burn them to erase history.
Did your FRiend also shoot the footage of Cruz with FPFC & SDSU protesters in Canada? (Assuming it’s French Canada and not France) The signage was all in French.
