All we can say is that in the nearly 30 years stories of snuff movies have been circulating, no genuine example has ever come to light. But pornography experts for the FBI and other law enforcement agencies say they have never seen a genuine snuff film.
Many people are convinced snuff films are real, possibly because it suits their ideological bent.
For example, in her book Feminism Unmodified , feminist legal scholar Catharine MacKinnon says flatly that snuff films exist. But when I asked her to elaborate she declined, and indeed was quite mysterious about the whole thing. She just knew. That's not to say there aren't movies purporting to show people actually being killed. News footage and the like in which a death is filmed by happenstance.
