Yeah..that's basically what CBS said. But, that link had one additional piece of information that CBS didn't broadcast:
"FBI agents interviewed Berg a few years ago when they were investigating the Sept. 11 terrorist attacks on New York and Washington, sources said. He was interviewed because, unbeknownst to him, Moussaoui had used his e-mail account when he was in Oklahoma."
So if the FBI had ALREADY interviewed Berg years ago, why the fuck would they detain him AGAIN in Iraq to go over the same crap?
