I.e. without larding on the max of "well, it was just stress"? After all we do have to allow for some berserkery (with no consequences, even so much as confinement in a mental hospital, because we NEEEEED those guys).
You do realize that the accusations about Hadditha all come from an "Iraqi Civil Rights Group" headed by a man that has the SAME name as a Major in Saddam's secret police? That this "Iraqi Civil Rights Group" filmed a supposed "survivor" a boy who supposedly was shot in the back of by "out of control Marines"? Only problem. In the CNN aired video "Haditha Uncovered" the boy "healed wound" is shown. The supposed bullet hole is high in his back directly over the spine. Only problem with that, if you shot someone at that point, you will shatter their spine. So the boy would be at a minimum, crippled for life. He moved around just fine on the video.
So since this so called "Iraqi Civil Rights Group" is LYING about this, what else are they lying about???
