What you are alleging might be true, were it not for multiple newspapers, both in the U.S., Britain and other European countries reporting on past instances of beheadings, with onlookers saying that it was Syrian rebels who commited the crimes.
Or are they in on it, too, part of the staging?
Believing that is akin to Trutherism.
Nonsense. I was not commenting on whether rebels behead people, including presumably innocent civilians.
I was commenting on whether this particular video is representative of the actual truth of what happened. And the truth is that a random video withpit provenance is proof of exactly nothing, except that a killing occurred.
Unless you are claiming that Assad and various other groups floating around the MI are much too high-minded to commit video murder in furtherance of whatever their cause is.
In video and images, context is everything.
IOW, for the video in question:
We don’t know when it was shot.
We don’t know where it was shot.
We don’t know who the killers are.
We don’t know who the victim is.
We don’t know the (real) reason(s) behind the killing.
