Thumbs Up, Four Stars
The Abu Ghraib investigation is taking a very interesting turn--seems that Maj. Gen. George R. Fay, who's leading the investigation, needs to turn it over to someone even higher ranking than himself (since Fay, a two-star general, can't question an officer of higher rank). Washington Monthly has a good synopsis of this, as well as some interesting news regarding an important witness:

Within the last several days, an important figure in the inquiry who had previously refused to cooperate with Army investigators suddenly reversed his position and agreed to work much more closely with investigators, a senior Senate aide and a senior Pentagon official said.

That important development prompted General Fay to send some of his 29-person team back into the field to conduct more interviews, the officials said. "A key witness, a key person who'd pled the military equivalent of the Fifth has changed his attitude, and Fay is reopening the investigation," the Senate official said.
