One path to that goal is to appoint a truth-finding panel. We could develop and authorize a person or group of people universally recognized as fair-minded and without an ax to grind. Their straightforward mission would be to find the truth. .As if.
Such a view seems to suggest one of three things: 1) the naivete of some liberals, 2) the hubris of some Congressmen, 3) deviousness. My personal pick is option three because I believe Leahy is still upset at Cheney for the F bomb. But even more sinister, he's a garden variety truther with respect to the anthrax attacks and seems to be part of a search and destroy mission currently being organized by his party, echoed daily by it's leader (something recently addressed by the Hitch).
Perhaps they've got visions of Bush officials on the stand defending themselves over the past as the 2010 campaign season gets underway, who knows.
Bring it on, though. Perhaps such a truth commission would be high profile enough to allow for some real truths to pop out at an opportune moment.
Bill Clinton and Tony Blair, fugitives from justice. Sort of puts this all in perspective, eh?
