"Stockholm syndrome" is completely useless term invented by guy who never spoke with the actual hostages. What the histages did was logical conclusion for their safety, where police was endangering their lives more than their captors.

"Nils Bejerot, a Swedish criminologist and psychiatrist, invented the term after the Stockholm police asked him for assistance with analyzing the victims' reactions to the robbery and their status as hostages. Bejerot never met, spoke to, or corresponded with the hostages, during or after the incident, yet diagnosed them with a condition he invented."

"According to accounts by Kristin Enmark, one of the hostages, the authorities were careless, and their initial approach to the robbers nearly compromised the hostages' safety.[6] Enmark criticized Sweden's prime minister, Olof Palme, for endangering their lives. Palme believed that if Olsson saw one of his close relatives, he might be willing to surrender the hostages; however, the police made a careless mistake. They misidentified Olsson, and sent a 16-year old boy who was unrelated into the bank. This caused confusion and resulted in Olsson firing rounds at the boy who barely escaped. Olsson became much more agitated in general. After that, Enmark and the other three hostages were fearful that they were just as likely to be killed by police incompetence as by the robbers.[7][8][9] Ultimately, Enmark explained she was more afraid of the police, whose attitude seemed to be a much larger, direct threat to her life than the robbers.[10]"
