Site your source. Actually, don't because there is no way I'm going to be able to change your mind.
Having seen the video, I can tell you that it was NOT fake.
OK let me explain something to you.
1. all videos Have something called TIMECODE which is measured in FRAMES. when the video is edited in any way those frames are what are actually being taken away not to mention the ridiculous cuts in the video like the one right when the lay him on the side then theres one where they're supposedly cutting and another after he is killed and motionless. He was Already dead when they started cutting him but we'll get to that.
I know this because my degree requires a lot of post production editing. hence the knowledge of time code. see? still want me to cite a source will my degree suffice? if not you could consult any number of video editing books.
2. basic anatomy. When you cut through the neck of a live person it is MESSY and I'm not talking horror film blood spatter. As soon as they lacerated the cartoid artery, blood would have Shot everywhere. His Blood pressure would determine the the speed and volume of the hemorrhaging But you would see a lot of spatter. I would have gotten everywhere all over the head the body everywhere. Unless he was already dead and had been dead for a significant amount of time. This also explains when the "terrorist' holds the severed head there is no dripping. As a matter of fact the head is completely clean.
How do I know this? basic knowledge of the human circulatory system. didn't you take health in high school?
3. People who follow the teachings of Islam believe that the Left hand is the unclean hand. Most who consider themselves to be true followers of Islam extremists included would not use the left or be dominantly left handed. yet in the video there are several "terrorists" who are left handed.
this information is also widely known and you can confirm it by asking somone who follows the teachings of islam but since its its pretty clear you don't have many Muslim friends, doing a simple google search will provide the same information.
so there you have three Questionable factors of the nick berg film. But don't take my word for it DO YOUR OWN RESEARCH. Look up video authentication. do a search for forensic anthropology read about islam. do anything but for God Sake stop watching fox. they'll have you spouting nonsense with a pickett sign and a teabag...
