Krugman has another interesting piece in the NYTimes today: 

There’s something happening here, and what it is seems completely clear: the Bush administration is trying to protect itself by purging independent-minded prosecutors.

Last month, Bud Cummins, the U.S. attorney (federal prosecutor) for the Eastern District of Arkansas, received a call on his cellphone while hiking in the woods with his son. He was informed that he had just been replaced by J. Timothy Griffin, a Republican political operative who has spent the last few years working as an opposition researcher for Karl Rove.

Mr. Cummins’s case isn’t unique. Since the middle of last month, the Bush administration has pushed out at least four U.S. attorneys, and possibly as many as seven, without explanation…In case you’re wondering, such a wholesale firing of prosecutors midway through an administration isn’t normal. U.S. attorneys, The Wall Street Journal recently pointed out, “typically are appointed at the beginning of a new president’s term, and serve throughout that term.” Why, then, are prosecutors that the Bush administration itself appointed suddenly being pushed out?

The likely answer is that for the first time the administration is really worried about where corruption investigations might lead.
