The Taliban's new top operations officer in southern Afghanistan had been a prisoner at the Guantanamo Bay detention center, the latest example of a freed detainee who took a militant leadership role and a potential complication for the Obama administration's efforts to close the prison. U.S. authorities handed over the detainee to the Afghan government, which in turn released him, according to Pentagon and CIA officials.
The relative word being detainee. Not convicted criminal. Innocent until proven guilty.
