It's a difficult case, and I understand why you see it as a tragic mistake, but I don't think the helicopter crew were sufficiently diligent in checking who they were going to kill, particularly in the aftermath of the first shots where people tried to help the wounded, and were then mown down. Just because someone was armed, doesn't make them an enemy (they could be for example a bodyguard for journalists), and just because someone tries to give medical assistance to others in a battle, doesn't mean they also need to be killed. Their callous reaction to the news that children were in the van having just killed their father demonstrates their lack of care.

At the very least Reuters should have been provided with this footage (instead it was covered up), and an independent investigation held.
