The use of the polygraph has done little more than create confusion, ambiguity and mistakes.

I found that our Soviet espionage efforts had virtually never, or had very seldom, produced any worthwhile political or economic intelligence on the Soviet Union.

The difficulties of conducting espionage against the Soviet Union in the Soviet Union were such that historically the Agency had backed away from the task.

The only thing I ever withheld from the KGB were the names of two agents whom I personally had known and handled and had a particular feeling for.

To the extent that I considered the personal burden of harming the people who had trusted me, plus the Agency, or the United States, I wasn't processing that.

Deciding whether to trust or credit a person is always an uncertain task.

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.
