Sound and Fury

Bill McGurn has a good piece in the WSJ on Attorney General Eric Holder and his increasingly precarious position amidst the gathering storm regarding the Fast and Furious scandal and the national security leaks at the White House.  McGurn luckily has a ready answer to Senators McCain, Graham, and Libermann regarding their talk of the old political standby of appointing a special prosecutor:

Perhaps after a few years and gazillions of tax dollars, a special prosecutor would give his results. What purpose, however, is served by keeping those answers to a prosecutor instead of to the American people? The proper vehicle for getting answers is Congress, using its oversight powers to conduct hearings and get the appropriate officials on the record and under oath.

Thank you.  It just seems that stuff is asserted all the time in politics that masquerades as common sense, but it's not.  And it's advice from someone who actually seems to be familiar with the Founders' designs.
