The Stockholm Syndrome is famous among pyschologists and sociologists. It refers to the intruiging concept, based on a prolonged bank robbery during which the hostages protected their captors when the police attempted a raid. Psychologists say that hostages often form sympathetic bonds with their captors as a survival mechanism. Survivors of an extended ordeal sometimes need to be deprogrammed back to the reality that they have been abused. International air passengers at Stockholm’s Arlanda Airport may well need some shrink-service.
