On the plus side, charging our own soldiers with crimes for friendly fire deaths on the battlefield shows how the U.S. is, well, not at all like our enemies. On the minus side, this sort of thing shouldn't be done lightly. Frankly, I'm not sure from the wire report whether this is egregious enough to justify charges, since a lot depends on whether the men were under any sort of a reasonable belief that it was impossible to safely follow the rules of engagement.
