I’ve been meaning to get around to commenting on Cecil’s “new evidence” on decapitated heads being aware of their fate: http://www.straightdope.com/columns/980612.html.
I’d like to respectfully suggest that people in the midst of a horror do not make the best eyewitnesses. For example, after earthquakes, people in 7-11’s will say that there were waves 3 ft high in the concrete floor, whereas the 7-11 surveillence camera shows no such thing. I would think that watching a friend being decapitated would be very traumatic, even for Army veterans.
