Somali Gen. Mohammed Samantar is not the only controversial émigré to hit American shores. The Center for Justice and Accountability has spent years trying to hold alleged war criminals accountable here for what they did in their home countries. Col. Nicolas Carranza, former vice-minister of defense for El Salvador, currently lives in Memphis, Tenn. On Nov. 18, 2005, a Memphis jury ordered Carranza to pay $6 million in damages for crimes against humanity, torture and extrajudicial killing. He has not, however, been imprisoned.
