It looks like USMC and NCIS have designated everyone civilians (don't know about the one Mendoza said he killed). The initial military payout was for 15 civilians, no money for 8 insurgents. Four of those insurgents were from house 3 (or 4). I'm 99% sure on those 4. I'm assuming the other 4 insurgents must have come from the taxi? Not sure why there weren't 5 from the taxi. I'm really not sure who the military thought the other 4 insurgents were.
Long story, short, the USMC and NCIS is now saying the four Marines killed civilians only, no insurgents.
I've got a question, who detonated the bomb? I don't think this has ever been answered.
I wonder if that can be infered. See post above.
Also the USMC official statement says that 24 Iraqis (not "civilians") were killed but Marines are not charged with 24 deaths.
