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.
No matter
Oswald is still in that 6th story window of the TSBD as Kennedy passes by underneath and all 3 shots have been evidenced to have come from that window with an almost absolute certainty AND beyond almost ANY doubt. He was seen in that window at that time.
Nothing else really matters.
