Well if
this article turns out to be true, then it starts to look more like a stupid mistake, or even gross incompetance. It's way to early to know for sure at this point of course. I'd be very suprised if it turns to be some sort of deliberate act on the part of the soldiers. Contrary to Iraqi propoaganda the US soldiers are not targetting civilians. They are getting themselves injured and killed in many cases going out of their way to avoid civilian casualties. That's not to say however they mistakes won't be made. And if it turns out someone didn't act quick enough and that caused or contributed to this tragedy they should be punished accordingly. But that doesn't make it a war crime.
I wonder if anyone has ever done a study of the number of French/Belgian/etc civilians inadvertantly killed by Allied actions during the liberation of Europe in WWII. Might be interesting, if nothing else for context.
