of course BBanner, someone has to do it and since no one else has...
First, war is hell. Civilian deaths are gonna happen. I'm not saying that it is acceptable to just let it happen, but it is going to regardless. War reporters/photographers are especially in danger, and they understand this risk when they go out to do their job. I'm sure they get paid highly in that line of work, as most dangerous jobs do. Reporters getting killed is nothing new, so they knew.
The video points out the cameraman and news people, but they fail to point out the actual weapons. [Watch this quick video to see them more clearly if you missed them - http://img708.imageshack.us/i/1270493174790.gif/] and if you watch the 4:08 time on the original video, then you see one of them getting ready to load and shoot an RPG.
If I'm in a helicopter, and they are aiming an RPG at me, then they are gonna die. There is no question in my mind that firing on the group of ~10 was the correct thing to do in that situation. These soldiers have to look out for themselves, and were given a very short time to decide what to do.
Shooting the van is less black-and-white for me. But again, if you think that they pose a threat, then you've gotta take them out. They didn't fire on the one wounded guy crawling away, until there was a threat. If a van comes into a war-zone, then it's safe to assume that it is not civilian? I don't know.
A couple questions come to mind (since I'm looking like the only one defending the soldiers :-) ). First, why were these two photographers so close to the group? They were just standing around with them. If I'm there, I get as far away as possible. America is known for its war technology, so at any moment there is the possibility that they are gonna engage, even if you don't see them.
Secondly, why bring kids into that situation? There is no justification for this at all. Even if the van is driven by civilians, what the hell were they thinking? You see 10 gun-downed people in the streets, you've got 2 kids in the car. What is your initial response? especially in a country that is at war.
