Wrong.
1. These folks aren't even covered as combatants, nor as civilians under the GC.
2. Before this incident the terrorists made a bad habit of falsely offering a white flag and then opening up when our guys exposed themselves. They also blew themselves up and their dead up with explosives. So even if you want to give them GC protection, they loose its protection when they break its rules.
3. Based on the above this Marine had every reason to shoot that terrorist. If you want to blame someone, blame the terrorists, they are responsible for forcing us to shoot first, ask questions later.
4. Had that terrorist had an explosive vest or grenade, like many have, and killed that fire team of Marines, what would you be saying now, "That's life." I suppose.
5. This happened in WWII in the Pacific on a regular basis. Like these terrorists, the Japanese were bent on suicide and would fake death, booby trap their dead, and feign surrender, just to kill one more Marine. It became common practice to shoot all Japanese that appeared dead before approaching them.
6. How about trying out your own theory. Go to the worst part of town at two in the morning and ask the first person you see on the street if they have change for a $100 bill. Keep trying that until you find someone kind enough to help you out. After all you don't want to assume the worst of people, you might hurt their feelings.
