Lifetime imprisonment without trial

The US is now considering ways in which they can keep suspected terrorists, whom they can't try due to lack of evidence, in prison for the rest of their lives. Unbelievable. Someone could more or less be snatched up by the American military for any reason, and never, ever be released, with no recourse and no chance to argue his or her innocence. I mean, I guess I understand that it's all in the name of freedom and democracy that the US has decided to become a totalitarian regime...

They have to be stopped. How? And who?
