It was claimed that before he was buried, Gov. Connelly should be examined for bullet fragments that some believed were left in his body. See my links 2 and 3 in comment #30. I do remember, because JFK was on the ballot for my first Presidential election as ayoung woman, and I followed the politics and assassination with great interest. The bullet on the gurney is not the other one which left traces in Connelly and could have proved that there was a second shooter, especially if the metal came from a different gun. So it was suppressed and that shlub Oswald remained the ONLY possible shooter. It was no doubt important to the people who planned the killing that Johnson carry on the Vietnam war without interference so his patrons could get richer.
As I recall, we were told that the records of the assassination would be closed as long as people who were alive at the time (like you and me) were still above ground.
JFK’s assassination was the “Where were you?” for people of our generation just like Dec. 7 and FDR’s death were for our parents. It no longer seems to be nearly the big deal that it was for us back then. Time passes, the dogs bark and the caravan moves on.
