There was no indication that the Terr was so wired.
When you are inside a building and you see a wounded terrorist who appears to be faking death, how close do you get to take a good look and how long do you look to determine this?
Sorry, but given the fact that the enemy is known to booby-trap themselves and fake injury to lure soldiers into a trap, I think it is only logical to err on the side of caution. At issue here is the fact that the Marine probably didn't know the man was injured. The Marine's cries of "he's faking death" seems to indicate to me that the Marine suspected a trap. Now, he may have been wrong about it being a trap, but if he DIDN'T KNOW, then how is he supposed to react?
Now, clearly this incident will be investigated, but in the meantime the MSM is already implying "war crimes". This is the part that ticks me off. Why not wait until the investigation has concluded? We just handed the enemy tons of propaganda without investigating this properly first.
