Oswald was framed—total no brainer.
Already released JFK assassination files prove he was on the second floor of the Texas Book Depository Building at the time of the assassination.
He was getting change for a dollar to use for the coke machine at the time.
There were several witnesses—their testimony was ignored by the Warren Commission.
There were multiple shooters—at least two on the Grassy Knoll and probably one on the sixth floor of the Depository Building and another at the Dal Tex building.
The “kill shot” came from the Grassy Knoll.
The absolute proof of CIA involvement is provided in the deathbed confessions of E. Howard Hunt found here:

Hunt was in charge of on-site logistics.
The CIA at the time was as “rightist” then as the CIA is “leftist” now.
However, why would the CIA want to kill Kennedy? Rather, why would the CIA think that Kennedy was such an existential threat—that he needed to be killed.
