In case you haven't been following the news, Wikileaks.org recently posted a video showing American helicopter pilots firing on Iraqis in Baghdad in 2007.  I've embedded the shortest version below the fold.

I won't rehash the whole saga here - check NYT or WaPo for the background - but the short version is that among those killed in the attack were two Reuters employees.  Reuters has been pressing the US military for information about the death of their employees without success.  Additionally, the attitude, disposition, and actions of the pilots has been called into question.  See here, here, or here for some insight into the issue.

I have two primary takeaways.

First, without knowing the ROEs and situation, I'm hesitant to condemn the pilots.  While I too find their language overly-enthusiastic, that alone doesn't make their actions wrong.
