Even if you're an American citizen, the government can detain you indefinitely and torture you, and there's nothing you can do about it.
Cutting through the legalese, that's the gist of the argument lawyers for former Defense Secretary Donald Rumsfeld are arguing in two cases involving the indefinite detention and alleged abuse of two American citizens. One, Jose Padilla, who was convicted on terrorism charges, is well known. The other is a John Doe, a veteran and defense contractor who was detained in Iraq and subject to so-called enhanced interrogation techniques. Both men are suing Rumsfeld and the government over their treatment. The cases aren't entirely the same, but they share enough of the basic legal issues that they're worth talking about together.
