Fruit Machine

During the Cold War, the Canadian military and RCMP worked assiduously to root out from their ranks, and from higher levels of the civil service, anyone thought to be homosexual or otherwise sexually “deviant.” Security officials exposed subjects to homo-erotic images and used a device that measured pupil dilation to determine whether the subject was aroused. The so-called fruit machine was bad science, and it damaged (and destroyed) careers, as did Cold War-era interrogations of suspected security risks associated with homosexual orientation. The distinguished, intellectually gifted, and unmarried Canadian diplomat Herbert Norman (1909-57) was grilled in the early 1950s regarding suspicions that he was gay; his subsequent suicide is thought by some to have been connected with his sexual orientation and fear of exposure.
