First we had the August "murder" on video of U.S. journalist James Foley, shown kneeling before a black-robed, masked figure brandishing a knife. Yes, even a rather small knife can do it (just as box-cutters can enable the hijacking of commercial airplanes). The perpetrator is identified as a member of the terrorist group ISIS (or IS or ISIL), which supposedly wants to install a new Islamic caliphate based in the region.
However, the video did not actually show the beheading, but faded to black at the appropriate moment. A subsequent frame purports to show Foley's head propped up on his headless body. This video was staged, however, as proved by numerous researchers, and even admitted in the British press.
According to a report in The Telegraph:
Nonetheless, the U.S. media continue to report this "beheading" as a real occurrence, over and over again, followed by another "beheading" of an American journalist, Steven J. Sotloff, in a video released in early September. This was supposedly a "second message to America" from ISIS: "Just as your missiles continue to strike our people, our knife will continue to strike the necks of your people." This video too is problematic, with no blood in evidence before the scene fades to black....a study of the four-minute 40-second clip, carried out by an international forensic science company which has worked for police forces across Britain, suggested camera trickery and slick post-production techniques appear to have been used...no blood can be seen, even though the knife is drawn across the neck area at least six times.
