The betrayal of trust carries a heavy taboo.

The human spy, in terms of the American espionage effort, had never been terribly pertinent.

The FBI, to its credit in a self-serving sort of way, rejects the routine use of the polygraph on its own people.

The U.S. is, so far as I know, the only nation which places such extensive reliance on the polygraph. It has gotten us into a lot of trouble.

Let's say a Soviet exchange student back in the '70s would go back and tell the KGB about people and places and things that he'd seen and done and been involved with. This is not really espionage; there's no betrayal of trust.

I'm a traitor, but I don't consider myself a traitor.

By the late '70s I had come to question the point of a great deal of what we were doing, in terms of the CIA's overall charter.
