See the difference? Blood immediately gushes because of the pressure well before what would have been the fade to black with the Foley video.
As well, there was also a second execution (well, at least a second man there in orange like Foley); the second guy looks like a bit chunkier guy of Foley.
I'm not buying any of this or zero's claims raids were done to save "hostages".
