@wtf,  did you watch the complete video? If you did, please watch it again. I am not saying that what they did was right because no innocent person deserve to die.
After knowing what really happened its easy to blame other people from the comfort of our home or apartment.  After reading all those news, we know that innocent person( journalist, his driver and the kids) were involved and were killed. We have  the luxury to look at the video over and over again and there was a arrow to show us  that there were kids in the van but from that unedited video, I don't really think what they did at that time was totally unjustifiable because from that raw video I couldn't tell if the person sitting on the passenger side of the video was a kid or adult. I agree the incident was indeed unfortunate and sad but I don't think you can totally blame the Apache crew. Yeah, everyone has their opinion and view so you are free to disagree with what I saw in that unedited video.And we are forgetting the fact that they found 'live rpg' on the scene. If they hadn't
attacked, they would have been attacked.
And did you guys notice how army personals were running with that wounded kid?

By stating this, I am not in anyway supporting what happened. US army should probably change the ROE but they can't blame those apache pilot because they were called to support  the land infantry who were being attacked by rpg.
