Protecting the reputations of long-dead Presidents has no relevance no us and our country.
We should see the records of all of the living Presidents as well and if there are crimes or malfeasance, the law should be applied. Our leaders and representatives are responsible to us.
BTW, I suspect that if the truth ever really gets out about the Kennedy assassination, we will probably owe the Oswald family big time and maybe erect a statue to Oswald if it turns out that he was framed.
Read Me and Lee by Judyth Vary Baker to find out just how victimized by the DEEP STATE which he served Oswald the Patriot was.
The Lincoln assassination investigation by Congress was similarly sealed. During and for a while after the Civil War, all the approaches to DC were under heavy armed guard. At one of the bridges leading out of the city, the officer in command rode up and told the soldiers on duty that at some point after dark, there could be a rider, and if legit, he’d give such and such a password. They said they understood, and the officer rode off. Some hours later, a horseman galloped up, was challenged, gave the correct password, and rode across, then on into the night. The rider was John Wilkes Booth. Odd that he had the right password, eh? :^) And there was no CIA in those days.
Uh, no.
