American fakes own decapitation in tape

All the more reason to question the authenticity of the recent execution videos. I have watched a few, most look realistic,- at least to me,- excepting the Nick Berg video. To learn more about Nick Berg's death and many suspicious circumstances surrounding it see this link and many others. I am not offering any theories of my own on what happened to the unfortunate Mr Berg,- I simply do not have enough information to go on. However, I suspect that the tape of his execution is a fake. Many people around the world have conducted expert investigations of that video and they also have serious doubts as to its authenticity.
