On the one hand, it's bad if released Guantanamo detainees who did nothing wrong are stigmatized in their native countries. On the other hand, it's a good thing if they are bad guys but are seen by fellow would-be-terrorists as potential American spies. That stigma makes the painful prospect of simply releasing scary people we can't put on trial (perhaps because of torture-tainted evidence) a good bit less frightening.
