A forensics expert points out hints that the James Foley beheading video was edited to give way to a change of actor.
Whiles experts has no doubt that Foley was actually killed, they were one in saying that the video showing his execution was edited to suit whatever purpose it wants to serve.
According to Ross Patel, a forensic expert, the change in stature of the man masked in black was a giveaway that there is another man or a second militant that acted the part. The second man could be the actual killer.
Patel pointed out that an obvious edit made it possible to conceal the appearance of the second man.
"There's definitely a change of actor. There are noticeable, there are subtle but there are also noticeable changes in their build, their physical appearance," the expert said.
Patel suggested that for investigators to track down the man in the video, the measurements of his face can be compared through databases of passport photos.
Patel was keen to observe that the knife being held by the man in the video has dimensions and style different from the knife left beside Foley's dead body and decapitated head. Furthermore, the man's pistol was holstered underneath his left armpit which suggests that he was right handed. However, the beheader who appeared in the video was left-handed.
Curiously, the whole footage appeared to be edited using "slick post-production techniques," according to an international forensic science company, which requested not to be named.
"I think it has been staged. My feeling is that the execution may have happened after the camera was stopped," the company's analysis of the video published by The Times reads.
Video experts, who had also spoken with The Times, observed that some portions of the video have play-acting.
In the instance that Foley's beheading video was elaborately edited using advance equipments, it will be logical to ask next as to how and where the ISIS gets its funding.
The group owns cash amounting to $2 billion amassed from private donations, taxes, ransoms and stolen millions of money from big infrastructures that the group had been seizing, The Guardian reports.
There is no way to determine the exact amount of funding that the group is getting, according to Australian National University's Middle East terrorism expert Dr Rodger Shanahan.
Shanahan said that it is a known fact that the group is amassing money from the Gulf to Syria, or their sales of oil from the locations that they now control. But as for the exact amount of money coming in, no one can definitely know "unless you're privy to their books of account."
Calling itself as a caliphate means that the group has its capacity to do everything that a government does as "the notion of holding dams is as much about claiming to be a government as it is about revenue raising," he said.
