I saw what appeared to be some rifles on some of the men in the first part of the video, so they were most likely insurgents. In the part where the van got plowed, I saw a man trying to aid one of those insurgents. I would not have known he was a journalist. I also saw two children in that van. I honestly might not have noticed them if they weren't pointed out. I'd be even less likely to notice them if I were there in the heat of battle(although my take on that has a caveat in that I'm not a trained soldier). It looks like a "fog of war" kind of mistake to me.

But having said that, I'd still like to see us finally wrap things up and bring the troops home from Iraq.
