"A U.S. appeals court on Friday threw out the first-degree murder conviction of a former Blackwater Worldwide security guard sentenced to life in prison in the killings of 14 unarmed Iraqi civilians in a Baghdad traffic circle in 2007."

"The four security guards opened fire on the Iraqis, including women and children, at Nisour Square."

How is this NOT a war crime or murder?  I was not there and have never been in combat so maybe I am lacking in such experience but, wow, that is a bit ridiculous.  How would we feel if some contract mercenary from China came in and killed 14 unarmed Americans - including women and children.  Somebody help me out here...?
