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

I handed over names and compromised so many CIA agents in the Soviet Union.

I knew quite well, when I gave the names of our agents in the Soviet Union, that I was exposing them to the full machinery of counterespionage and the law, and then prosecution and capital punishment.

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

Perhaps my information hurt the Soviet Union more than it helped. I have no idea. It was not something I ever discussed with the KGB officers that I was dealing with.
