No, it's much more complex than that. Some of the men were very clearly armed, which anyone who watches the video can see for themselves. Even Assange acknowledged this fact.

The most legally questionable part (I believe) is firing on the van that was evacuating wounded people. The best ethical defense to that attack was that they didn't know children were in there and the driver is primarily to blame for what happened to them.

But even if it was most likely an ethically wrong decision, that doesn't make it automatically illegal.

Even without children in the van, is it legal to fire on an unarmed person in a van picking up the wounded?

And all these arguments are spurious IMO. Collateral Murder exposed what was being done secretly overseas in US citizens' name.

If it wasn't illegal then there should be no problem showing their people exactly what their war budget is paying for.
