In 1974, Patty Hearst, a member of the wealthy Hearst family, was kidnapped by the Symbionese Liberation Army, a left-wing militant organization. After several weeks of captivity she agreed to join the group and took part in their activities. In 1975, she was arrested and charged with bank robbery and use of a gun in committing a felony. Her attorney, F. Lee Bailey, argued in her trial that she should not be held responsible for her actions since her treatment by her captors was the equivalent of the alleged brainwashing of Korean War POWs (see also Diminished responsibility). Bailey developed his case in conjunction with psychiatrist Louis Jolyon West and psychologist Margaret Singer. They had both studied the experiences of Korean War POWs. (In 1996 Singer published her theories in her best-selling book "Cults in Our Midst".) Despite this defense Hearst was found guilty.
