From MountainRunner's post:
The "rebuttal" video was removed from YouTube for "violation of the YouTube Community Guidelines." The cause of action: "graphic or gratuitous violence is not allowed in YouTube videos." The "rejection notice" at right was sent by someone close to the "rebuttal". Neither Collateral Murder nor the unedited video have been removed from YouTube.
Elsewhere in this thread others have raised the (valid) question "how many insurgents did we create that day?" Whatever figure answers that, it's lower by far than the number created by the release of this video (a true global sensation) nearly three years later. Since any greater number increases Wikileaks' chances of getting more snuff porn for future audience enjoyment I suspect they'd call that a "win".
