Capt Kimber claims he was away from town during all of it. He went public claiming just that. He's claiming he never heard anything about it, he was out of town and that the Marine Corps is unjustly punishing him for it. Last I heard he was promising to go on SoCal radio claiming he's the same. link If Kimber is now saying he knows all about this, then he was probably relieved for lack of confidence, because he can't get anything straight.
Read his quote. He does not KNOW about the "massacre" because he was fighting elsewhere that day. But he DOES know that following the "massacre" he heard nothing about it. From his fellow Marines, from Haditha City leaders and councilmen WHO HE WORKED WITH after that day. He heard about it from the press, which heard about if from the Hammurabi sources mentioned in this article.
