The Five Monkeys Experiment

I didn't know quite how "attached" it was possible to get, when looking up Stockholm syndrome:

On August 23rd, 1973 two machine-gun carrying criminals entered a bank in Stockholm, Sweden. Blasting their guns, one prison escapee named Jan-Erik Olsson announced to the terrified bank employees “The party has just begun!” The two bank robbers held four hostages, three women and one man, for the next 131 hours. The hostages were strapped with dynamite and held in a bank vault until finally rescued on August 28th.

After their rescue, the hostages exhibited a shocking attitude considering they were threatened, abused, and feared for their lives for over five days. In their media interviews, it was clear that they supported their captors and actually feared law enforcement personnel who came to their rescue. The hostages had begun to feel the captors were actually protecting them from the police. One woman later became engaged to one of the criminals and another developed a legal defense fund to aid in their criminal defense fees. Clearly, the hostages had “bonded” emotionally with their captors.
