Everyone already knew or believed that and/or consider it irrelevant to the crime.
Keep chasing your own tale and get back to me in a year or two.
Wrong—the “conspiracy theory debunkers” from the Warren Commission to several authors who defended the Warren Commission (and all mass media) insisted that Oswald did not work for the CIA.
They claimed it was a crazy conspiracy theory.
It is now a conspiracy fact.
Here is one example of a Washington Post article in 2017 arguing that Oswald did not work for the CIA:
“MR. HELMS: Mr. Belin, this question, and I think you may recall this, was raised at the time and the Agency was never able to find any evidence whatsoever, and we really searched that it had any contact with Lee Harvey Oswald. As far as the FBI was concerned, my recollection is not all that precise. I believe that Mr. Hoover testified that he had not been an agent of theirs either. He was certainly not an agent of the CIA. He was certainly never used by the CIA.”
Former CIA Director Helms told the Warren Commission that Oswald did not work for the CIA.
Helms lied—and the Washington Post believed the Helms lie.
