President Barack Obama signed a law on New Year's Eve granting himself absolute power to indefinitely detain American citizens suspected (by him) of being "belligerents." He promises he won't use it, however.
On December 31, 2011, with the President's signing of the National Defense Authorization Act (NDAA), the writ of habeas corpus — a civil right so fundamental to Anglo-American common law history that it predates the Magna Carta — is voidable upon the command of the President of the United States. The Sixth Amendment right to counsel is also revocable at his will.
The United States, as Senator Lindsey Graham declared during floor debate in the Senate, is now a theatre in the War on Terror and Americans "can be detained indefinitely ... and when you say to the interrogator, 'I want my lawyer,' the interrogator will say, 'You don't have a right to a lawyer because you're a military threat.'"
