If the CIA had ever been competent, instead of failing to gather helpful intelligence during the Cold War because Russia was always one step ahead of them, they would have already had this file. But then again, if it says the CIA murdered JFK, then there’s no way they would have tried to get it.
I heard that the same document WAS previously handed over, like in the time of the Warren Commission, to the Clowns In America. It was likely destroyed, dog ate it, or they had a boating accident with it.
