Findlaw columnist and Human Rights Watch official Joanne Mariner today examines the plight of those "enemy combatants" being detained outside of Guantanamo Moussaoui and the Hidden Detainees:

The most important aspect of Zacarias Moussaoui's prosecution may have little to do with Moussaoui himself.....The larger significance of Moussaoui's case lies elsewhere. It is, at present, the only legal peephole by which to glimpse the circumstances of a much more important group of terrorist suspects: those, like Khalid Sheikh Mohammed and Abu Zubaydah, who are held by the U.S. military for interrogation in "undisclosed locations."

....Right now, the detainees are missing, "disappeared," vanished with hardly a trace. No one knows where they are, and little is known about how they have been treated, although disturbing reports are occasionally leaked. These hidden detainees are in a frightening legal limbo. It is time for the judiciary -- and the Supreme Court, eventually -- to step in.
