You need to watch the video again. This time, turn off the sound and ignore the captions.
A man covered in blood is crawling along the side of the road as you drive by. You say, "My god! This man is injured! We need to help him!" You and your friend jump out to help an injured man, not really sure what's going on, and tell your children to wait in the car. Suddenly you're dead, because a helicopter flying high overhead killed you instantly because you were moving an injured man.
That isn't a hypothetical, that's what happend. And if you ignore the chatter of a few pilots eager to score more kills, it's very clear that these people had no connection to any activity on the scene. The Van is nowhere in sight until the very end of the engagement.
What's more, it's clear the pilot is eager to kill. He reports it in the most biased of terms: mentioning they were "possibly recovering weapons" despite seeing NO such action. How do we know he knew such a thing, you might ask? Because just moments before he was literally begging them to pick up a gun so he could kill them, and in the end he got a fire order anyways because of a biased report.
The actions of the pilots in that video were reprehensible and it is unfortunate that they will most likely be shielded from prosecution. On that day they ceased to be revered servicemen for the united states and became a representation of every flaw in our military system that Americans revile. They teetered on the edge of becoming war criminals. At the very least they should be dishonorably discharged.
