Meet the National Defense Authorization Act, 2012.

This bill says that anyone suspected of having "committed a belligerent act" could be detained indefinitely--without charge and without trial. The original wording of it specifically exempted American citizens from this, but according to Senator Carl Levin, that wording was taken out, and it was the current administration who wanted it taken out.

Granted, the new wording doesn't specifically say that American citizens are NOT exempt, but it says nothing either way, only that "any person who has committed a belligerent act" could be held indefinitely. The bill does not define what that means in the new language, if I'm understanding it correctly. It COULD be interpreted to include American citizens, especially if the administration took out the wording that specifically exempted them.

What's more, apparently the fate of this bill could be decided as early as tomorrow.
