I caught some TV archive footage from a Netflix program about Son of Sam (David Berkowitz)... There was a psychologist on TV who objected when someone said he had expertise with serial killers. He replied that nobody in psychology had expertise with serial killers, because there are simply too few serial killers who are in therapy. The psychology of killers has a lot of allure but the way it's portrayed in the media (Silence of the Lambs, Criminal Minds, etc.) has little to do with reality.
