Sure it's understandable that it wasn't right that a few Marines killed a few civilians, but it might have been good. The people that are killing our troops are roadside bombers and suicide bombers so some of those "innocent civilians" might have been the Iraqi's that are placing bombs for our American troops to walk over and detonate them or strap on explosives and kill even more people when they blow themselves up . I mean its not like these Iraqi's are wearing uniforms while they are placing bombs for american convoys to run over, they are just plain looking civilians and if you consider what America has done to "innocent civilians" look no further then the two atomic bombs we placed in Japan in WWII....
