I'm sure Murtha doesn't want to give up his sources b/c they probably were just giving opinions of their own and didn't know any more than he. He'd have to state that they were heresay, and not known for their accuracy.
It is my guess that Murtha wont give up his "sources" because there were no sources to begin with.
The liar made it up as he went along.
Some one needs to hang for this. I dont mean metaphorically, nor do I mean any of the currently accused Marines, officer or enlisted.
This entire affair has been nothing but an overt and direct aid and comfort to our enemy. Start with the reporter that agitated in support of the known insurgent loyalist that started this bullcrap, add in any officer of any branch of the US armed service that signed off on this bullcrap and then end it with the politicos that have been playing up this bullcrap.
Every one of them are traitors and should suffer a traitor's death.
If he doesn't answer, charge him with OBSTRUCTION OF JUSTICE, like Scooter was.
