I agree. I sure that's what the marines told the reporter. Being embedded with the marines,being shot at together and seeing how the terrorists try to trick US troops by playing dead for instance, the marines thought they could trust the reporter. Unfortunately, they were sadly wrong. This reporter to me is a Quisling.
You're right. And that reporter should rot in Hell for this episode.
Re: This reporter to me is a Quisling.
IMHO - the reporter saw it differently, apparently.
He had to report it if he believed a summary execution had taken place. Combat folks can't summarily take out a wounded, unarmed combatant. Marines know better. That's why it must have been that the situation was seen as life threatening by the marine who shot the wounded combatant.
