Judging by the pictures that have come out. the Marine was well aware that the wounded man was NOT boobytrapped. Had he been and killed at such close range, the resulting explosion would in all likelhood have taken out the Marines standing in the area.

In the same way I will always believe that our government knew very well that Saddam did NOT have WMD or they would not have invaded. They knew Korea and Iran did have weapons that could have been used against us - and they didn't go there.
