It would be a hard sell for the military to say, 'He violated the ROE, and if anyone else does they'll be punished, but we'll let this Marine slide because his violation became a media event'.
It would be an easier (and more honest) sell to say, 'The ROE isn't based on common sense for the situation, and it puts troops in unnecessary danger, so we're changing it', but I doubt they'll sack up and do it.
We are the knights that say QIF!, QIF!
