I guess most of "Faces of Death" scenes are fake too:
Faces of Death: Possibly the most famous of all films pointed to as "snuff" is the Faces Of Death series, a sequence of six videos made up of footage of accidents, suicides, autopsies, and executions, liberally peppered with outright fakes scenes. Most of the actual death scenes shown in these films are of the post-death variety. The multiple camera angles give away the acted-out nature of many of the most compelling scenes.
