At the beginning of the video, I can sware I see a guy with RPG hiding behind the building. And two camera men, yes.
Looks like they tried to shoot some pictures in a style "another anonymous terrorist guy with an RPG behind the wall".
You can call me moron, but I'd definetly shoot them.
And if I were in place of people who try to save some victims on a bus, I'd stand there with arms up.
Thats war.
