Car bomb the messenger

A Marine shoots an unarmed and wounded insurgent at point blank range in the head in violation of the morals and higher humanity that we claimed were the reason we went into Iraq, and people are actually upset with the fact that the media actually reported it(language)?

And some seem to propose that we devolve to the level of the terrorists rather than try and maintain any sort of higher moral ground. Car bombs for everyone!

Heck, we already kill civilians trying to escape the carnage anyway. Why not go all the way?
