The video was obtained by an organization called "Wikileaks". In this 2007 video we can see gun camera footage from the chopper as they try to identify some people with "weapons". It turns out that they fired at two video photographers, Namir Noor-Eldeen and Saeed Chmagh, working for Reuters. Both were killed in the attack. The chopper even fired at a van that is trying to pick up the injured. In a dozen civilians were killed and even two children were hurt by the weapons fire.
In all fairness, sometimes these mistakes happen in the heat of battle. But no battle was being waged. And even thou some of the movements look a little suspicious, still a "wait and see" attitude may have helped avoid these deaths.
Is this the way we treat those who we were supposed to liberate?
I have included the complete version of the video. You be the judge.
The video contains graphic violence and death. Viewer discretion is advised!
