Oh god, why do people keep thinking this and continue to talk about it? Why do plausibility and real-world events constantly get thrown out the window for some ridiculous fairy tale that Lifton cooked up and made a million bucks on?
How in the world would anyone know that early in the game what could possibly have happened in Dallas to start some stirring of stealing the body and performing all manner of body alterations? They had absolutely NO IDEA at that point what happened on Elm Street. None. So how in the world would they even know what to alter? And yet, to this day goofy people STILL believe goofy stories like the body being thrown down into the cargo hold and whisked away on a helicopter in full view of the widow, his brother and live TV cameras and TV lights. Whisked away so mad doctors with scalpels at the ready did "all manner" of body alterations.
Why? Why do people still believe this crap?
