The Warren Commission asserted in 1964 that Oswald visited Mexico City from Sept. 27 to Oct. 3. The implication was that his activities there showed his pro-Communist and anti-American mind-set.
But the seven-member commission and its investigators disregarded significant questions about whether Oswald undertook his years of post-military and seemingly anti-American activities as an undercover federal agent playing a role. Oswald joined the U.S. Marine Corps as a teenager and won a high-level secrecy clearance because he worked at the Atsugi Air Force base in Japan on the secret U-2 spy plane overflights of the Soviet Union and China. He defected to the Soviet Union after learning to speak Russian in the Marines, but developed extensive contacts with CIA, FBI, and military personnel upon his return from the Soviet Union in 1962 with U.S. government assistance for him and his Russian-born wife.
After Oswald's arrest in 1963 after Kennedy's killing, he tried unsuccessfully to phone from the Dallas police station a contact in Nag's Head, North Carolina. That was the location of the Navy's secret "false defector" program during the 1950s. The locale trained personnel to defect and act as double agents, according to numerous sources quoted by Richard Belzer and David Wayne in Hit List. Their expert sources included U.S. Senator Richard Schweiker and former high-ranking CIA executive Victor Marchetti.
Some scholars, including James Douglass in his 2008 best-seller JFK and the Unspeakable: Why He Died and Why It Matters, argue that the CIA and allied authorities sought to use imposters and false paperwork to create suspicions of pro-Communist and erratic behavior by Oswald to help confirm his guilt in the public mind after the assassination. Remember the title of the Douglass book. As explained below, the word "unspeakable" is relevant to the Pope Francis address to Congress last week and to each U.S. citizen.
Beyond such questions about the JFK assassination, the debate this month over the CIA's 1963 PDB on Oswald illustrates why official documents are not always accurate even when they describe, as here, secrets never expected to become public.
Therefore, those relying on such research should always regard such documents as a tool but not necessarily the truth.
