Disgusting, but not unusual at all.
I especially like this part:
“Well there’s no question in my mind, what happened was an IED exploded. It killed one Marine. And then a taxi drives up. When the taxi comes up there’s four of five people in it. And they shoot … shoot those four or five people unarmed.
I always wondered about that. If a car drives at you, in a country known for cars being used for suicide bombings, the driver knows that the cars are being shot at when they drive towards convoys at high speed and don't stop, and it's happening right after an explosion and during a firefight, and the driver doesn't stop (as any sane person should've done), it's just natural selection in a war zone (for all that we try to pretend that Iraq isn't a war zone, but "a country on the way to recovery) - the dumb get killed. Then again, that Murtha guy sounds like he's made up his mind way before he learnt anything about this incident (probably, way before the incident has happened), and so anything that doesn't fit his picture, his great cause, isn't worth thinking over.
The usuals, whatever I post is my opinion, yaddayaddayadda. I'm still learning this, so if you listen to me, well, good luck to you :)
