When a head is cut off the blood will spurt all over.
Local speculation here is he was drained of a lot of blood. Just see how pale (spaced out? passive?) he looks. So the videotaped "beheading" wouldn't be so bloody. The Islamic scum who killed him were worried about cleaning up a bloody mess and a video that would appear too violent for world opinion.
MHO is he had some blood sucked from him to make him weaker, more submissive to the final knife. Very evil sh*t !!!
WOuld that be the case for the Russian beheaded by Chechens? His blood didn't spurt either.
In fact, I don't think it's true that blood has to SPURT, it may pour out or what have you, but if that Russian POW video is any indication, blood need not spurt out when a head is being sawed off.
