I looked into the real CIA agent who was working for the Soviets. He was living like a king for many years. It boggles the mind that the CIA didn't pick on the fact he was trading info for money. I guess that because he passed polygraph tests, they didn't put him under too much scrutiny.
He said that in order to pass the polygraph, he just relaxed and made friendly talk with the examiner. It worked. lol It took them many years to catch. I don't think he was charged until 1993! That's amost ten years after when the the tv is set.
