We don't have enough information from reliable sources to believe or disbelieve. Far too many are eager to believe the worst about Marines, and are already preparing their protests for the "perpetrators" not being punished severly enough.
The propagandists will say, "we always told you the Americans were really heartless killers, and now you have your proof."
And we will say, "that was one small group under bad leaders, and two incidents thirty years apart."
And they will say, "it could happen again at any moment because Haditha was when their true nature was revealed." (If we're lucky. If we aren't they'll just gin up more examples.)
I think your quoting someone,is it Kerry.Not our Marines.
