1986: A year after CIA counterintelligence officer Aldrich Ames began betraying secrets to the Soviets, the American spy agency scheduled a lie detector test for him. Although it was only a routine test, it put the wind up Ames.
He got in contact with the KGB and asked them to suggest ways to foil the polygraph. Their advice: “Get a good night’s sleep, and rest, and go into the test rested and relaxed. Be nice to the polygraph examiner, develop a rapport, and be cooperative and try to maintain your calm.”
