This is an amazing story, I think, with the potential for extraordinary consequences:

Until four months ago, Col. Morris D. Davis was the chief prosecutor at Guantánamo Bay and the most colorful champion of the Bush administration’s military commission system. He once said sympathy for detainees was nauseating and compared putting them on trial to dragging “Dracula out into the sunlight.”

Then in October he had a dispute with his boss, a general. Ever since, he has been one of those critics who will not go away: a former top insider, with broad shoulders and a well-pressed uniform, willing to turn on the system he helped run.

Still in the military, he has irritated the administration, saying in articles and interviews that Pentagon officials interfered with prosecutors, exerted political pressure and approved the use of evidence obtained by torture.

Now, Colonel Davis has taken his most provocative step, completing his transformation from Guantánamo’s chief prosecutor to its new chief critic. He has agreed to testify at Guantánamo on behalf of one of the detainees, Salim Ahmed Hamdan, a driver for Osama bin Laden.

As outspoken as Col. Davis has been (remember, he’s the source for the story in which DOD Gen Counsel William Haynes blanches at the idea of a system that results in anything but a conviction), I suspect there’s a lot more to be heard.  And when might we hear it?

“I’m hoping at some point to retire, so I can say what I really think,” he said.
