This sounds like something John Conyers cooked up, as he is a Congressman for Detroit. Can you imagine him being the leader of the Judiciary Commitee? If you want to see something really funny, check out Conyer's web site. He is trying to appeal to the Kos nuts.
More than that, he's trying to get enough evidence to begin impeachment proceedings against President Bush. This (the judge's ruling) is a first step. Next step is getting to be Judiciary chair if the Rats take Congress this fall.
