In light of the Supreme Court's recent decision that prisoners of the American state actually have some natural rights, Republicans like Sen. Lindsey Graham are actively vowing to do everything they can to make sure that habeus corpus (and most of what remains of the Bill of Rights) will be eliminated from our legal system forever.
Graham and the GOP all want judges like Scalia, of course. Judges that will conclude that the government can kill, imprison, and rob anyone it wants at any time as long as the state has decided it has a good reason to do so.
John Paul Stevens is on his last leg. If he's replaced by another Thomas or Scalia clone, you might as well start packing your bags for some secret federal cage ASAP.
