And about the kids...
As far as I know the soldiers didn't know kids were in the van, how could they have?
Also if we as Americans won't shoot when kids are around, the "terrorists" could carry a kid around all the time for immunity. Same can be said for a journalist vest....
That is part of why our soldiers jobs are so difficult. It's very difficult to decide who is "good" and who is "bad". So being like "ahhh we're gonna risk it and let him go, even though that looks like an RPG" just doesn't cut it..
