Did you also know that Oswald defected to Russia, then was allowed to come back? That's one of the bizarre factoids that the conspiracy types show "proves" he must have been working for the government. Why else would they let him into the country? As if Che Gueverra wouldn't have gotten into the country!
Interesting stuff. I remember Oswald going to Russia but not that he defected. If so, that would make it even more bizarre.
Oswald's wife was Russian, if I remember right, and there were numerous rumors of her being a spy at the time.
The unit he served in was MACS-6 (Marine Air Control Squadron 6). I was with that unit in 1967 prior to going to Viet Nam.
