There only Iraqi arn't they?

Four years later, the U.S. military still has rules in place that permit the killing of civilians in airstrikes. In fact, the number of anticipated civilian deaths is carefully appraised beforehand in a calculation known as the collateral damage estimate, which is then reviewed by commanders and military attorneys who must decide if the benefits of the strike outweigh the cost in innocent civilian lives.

When is an accidental civilian death not an accident?

When the Air Force asks permission first. In Iraq and Afghanistan, the U.S. military has rules for killing civilians. But do the rules actually save lives?
