Watch the Smithsonian Associate's lecture at the International Spy Museum, "What Makes Traitors Tick?" David Charney gives this presentation based on his article, True Psychology of the Insider Spy. Dr. Charney was the psychiatrist for notorious spy Robert Hanssen and interviewed him extensively in prison. He knows better than anyone how Hanssen felt immediately after his long-term espionage was discovered. Did Hanssen feel remorse, did he worry about his family, did he care? The answers may surprise you. Charney has worked with a number of high-profile spies, and has focused extensively on the psychology and motivation of traitors.
