Afghan civilians killed by US airstrikes

" The NATO mission in Afghanistan has opened a preliminary investigation into claims that more than 20 civilians were killed in recent American airstrikes in the southern province of Helmand, military officials said Saturday."  Let me save US tax money and time:  the investigation will conclude either that 1) it was justified in self-defense; or 2) it did not happen and that the victims were all terrorists, even those who were toddlers.
