Shenon, in his extensive research, suggested that in 1963, an FBI informant affiliated with the American Communist Party, tipped off the agency when he told them about his run-in with Castro in Havana.
Castro allegedly told the informant that Oswald, a defector and political dissident, once walked into a Cuban or Soviet embassy in Mexico City and said he was going to kill Kennedy.
Shenon said the remarkable claim, which was documented in a letter from J. Edgar Hoover to the Warren Commission in June 1964, eventually disappeared.
In his estimation, Shenon told NPR the remark should have inspired “a million questions about whether or not people in Mexico City were aware Oswald was talking about killing the president.”
But after talking with members of the Warren Commission, Shenon reported that some were convinced they never saw such a record. Nonetheless, they were angry to hear that it might have existed, swearing that a much more aggressive investigation would have taken place had they known.
In addition to these curiosities surrounding Oswald, declassified reports also revealed that despite months of FBI surveillance tracking him in Washington, D.C., Texas, Louisiana and New York, he never made it onto the FBI Security Index, which names individuals considered to be a threat to public officials or national security.
Conspiracy theory is something human beings naturally show an affinity toward, Logevall noted.
“I think because we, as human beings, like to think about what’s beneath, what’s hidden. Second, I suppose that there is a certain comfort that comes from imagining that something hidden is driving human events, especially big events like this and that they’re not merely the results of one twisted individual’s actions. It makes for a more intelligible universe for some people,” he said.
Logevall said it is surreal that this year’s final chapter in a renowned conspiracy will end during the administration of a president who openly traffics in conspiracy.
President Donald Trump’s labeling of special counsel Robert Mueller’s ongoing Russia probe as a witch hunt and claims that climate change is a “Chinese hoax” make for strange juxtapositions, he said.
“It is ironic that our greatest, or arguably greatest, conspiracy theorist now is in a position to make this decision. He’s somebody who at least seemed to suggest that [Republican U.S. Sen.] Ted Cruz’s father was implicated in this assassination,” Logevall said, pausing for a moment. “Now he gets to make this decision? That’s ironic.”
A moment for transparency, and perhaps even cultivating goodwill, now presents itself to Trump. Had the government decided to be more transparent during the investigation of Kennedy’s murder initially, it might have helped put some questions to rest, Logevall observed.
“It seems to me that the time is now,” he said. “It’s time for the federal government to make this release, to show what it has. I think the time for full transparency on this issue has come. To the extent that it can help, and it would be a small amount, but to the extent that it can help rebuild Americans’ trust in the federal government, it should be encouraged.”
If Trump decides to bar the release of the remaining JFK records, it would only reinforce overall skepticism, he said.
Logic suggests nearly six decades later, most – if not all - of the individuals named in the files are long dead. Spy identities or mission details are all unlikely to upset national security today.
But might there be hesitation to expose the inner workings of a secret agency during a time when the U.S. government is investigating a foreign country’s meddling in the last presidential election?
Logevall said he could see it being problematic but still believes the “burden of proof” to clear away conspiracy theories falls on the federal government.
At the 50-year mark of Kennedy’s death in 2013, a survey by the Associated Press found that 59 percent of Americans believe multiple people conspired to kill Kennedy. Twenty-four percent believed Oswald acted alone, while 16 percent were uncertain.
Until October, speculation on the contents of the remaining files ranges from the mundane to wild theories reminiscent of best-selling spy novels.
The most tantalizing prospect? Possible surveillance reports on Oswald during his trip to Mexico City two months before he killed Kennedy that could indicate foreign co-conspirators, and the release of a tightly held 221-page file on Viola June Cobb, a beautiful blonde student turned spy who once told CIA bosses she could identify witnesses tying Oswald to a Cuban plot involving spies spread over Cuba and Mexico City.
That would be a very long shot, both Logevall and Czitrom agreed. They both also feel that Oswald acted alone, “full stop.”
But could the soon-to-be-released information expose secrets of foreign intrigue and domestic bungling that led to JFK’s assassination?
Until it’s all out, “you can’t prove a negative,” Czitrom said.
“There’s no real smoking gun, especially in regard to a foreign power. And that could have resonance today, given today’s Russian investigation,” he added.
No matter what comes from the release, assuming the records are released, the important thing to focus on, both historians agreed, is the legacy of the former president’s life, not his death.
“I’ve thought about this a lot during the rather dismal election season,” Logevall reflected.
He added, “Kennedy’s belief in politics, that government, though it can’t solve all of our problems, can be a force for good in society. He had a love of politics, but more importantly a belief in what it could do. It’s often said he is an inspirational figure. That’s one of the most important things a leader can be. Kennedy inspired Americans to believe in something bigger than themselves. He had a visionary notion of what it means to be an American; their rights and responsibilities of citizenship. I worry a bit that we’ve lost that capacity to believe in ourselves because we’ve become so cynical. We tend to mistrust one another’s motive. That’s a real problem.”
