Yeah, something doesn't seem right about that video. After the shots you clearly see her right arm and there is no sign of blood. When she is in the van it "appears" and it looks dried somewhat. There seems to be a second cut on the side of her hand which suggested to me she cut her hand falling down - it could also explain the cut further up her arm, small pointy rocks on a tar sealed road do that kind of damage.
Maybe if she didn't enjoy showing all the crew her bleeding so much, and they had just shown the real video without the "cut scenes" afterwards... it might have some creditability. Also how do you get two cuts and from one bullet?
Speaking of creditability and propaganda... those guys are supposed to be releasing the details about the dead yeti they found today... heh... we have just a bad photo as proof at the moment. *sigh*
