Having endured 14 years as "the most tortured man in Guantánamo," Mohamedou Ould Slahi has been denied a passport from his native Mauritania to seek medical treatment abroad for the effects of his detention and abuse - a refusal lawyers deem a brutal extension of "the extrajudicial punishment" of a man who was never charged with or convicted of a crime. Now "a prisoner in my own country," Slahi vows he "will get my rights peacefully" just as "everybody wants, my people and your people."
