I think that collateral damage is acceptable and even unavoidable when in a war zone. Compared to here in the US where you're not in a war zone, even in Chiraq.
So most ROE may say if a threat appears to you at that time.
So could they investigate Eddie for the pic he took. Of course. But they wouldn't put him in jail until his trial if he goes to one. He may just take a plea deal and reduction in rank or something to save time. Take a pic of a dead combatant is way diff from killing an unarmed combatant who is wounded. And like I said, video clears him 100%, so at most, confined to his barracks during investigation. Watch the 20 min vid and say "OK, you're free to go".
So in the end he did get fucked by the green weenie (not sure what they call the navy one).
I remember watching an ethics class at Annapolis. They asked potential pilots, what if you're given orders to destroy an enemy convoy? But as your plane pulls up, they waive a white flag. Do you fire or not? Because if you don't then every time the enemy hears a plane, they will wave their white flag so they don't get bombed.
Another one was if you're on a ship and have to rescue a Cuban raft, the kind they used to flee from Cuba years ago to go to Florida. A woman is pregnant on that raft and you allow her on the US ship. That US ship is US soil. So if she gives birth aboard, her kid is a US citizen. Do you allow her on the ship, or leave her on the raft, or give her a US navy raft that's more sturdier and send her along her way?
