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

I saw a limit to what I was giving as kind of a scam I was running on the KGB, by giving them people that I knew were their double agents fed to us.

The national security state has many unfair and cruel weapons in its arsenal, but that of junk science is one which can be fought and perhaps defeated.

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

An espionage organization is a collector: it collects raw information. That gets processed by a machinery that is supposed to resolve its reliability, and to present a finished product.

I could have stopped it after they paid me the $50,000. I wouldn't even have had to go on to do more than I already had: just the double agents' names that I gave.

I said in court a long time ago that I didn't see that the Soviet Union was significantly helped by the information I gave them, nor that the United States was significantly harmed.
