And here comes the inevitable "it's all the media's fault": Among the many disturbing images included in the "manifesto" Cho Seung-Hui sent to NBC is a photo of the Virginia Tech killer wielding a hammer in a manner somewhat similar to a scene from Oldboy, the ultraviolent revenge film from South Korean director Chan-woo Park. Or so says VT professor Paul Harris, whose hypothesis was soon picked up by the London's Evening Standard and repeated all around the world, with some commenters in online forums going so far as to say Cho's entire massacre was based on the film.
