The Massacre at Haditha..is this for real?

I just found these links over at Rory Shocks blog. I read them and was speechless. This purports to be a blog. of a Soldier in Iraq located in Fallujah. This link is to the Time Magazine web edition entitled: Collateral Damage or Civilian Massacre at Haditha? The article and the soldiers blog allude to 15 unarmed Iraqi's, of which 7 were woman and 3 were children were killed by American Soldiers.
