Bushco - gangster motherfuckers:
In earlier cases of prisoner abuse in Afghanistan, the alleged victims either were dead or unidentified. Other alleged victims in Driver's case also cannot testify. One was released from custody and cannot be found, and the other has died.
This witness, due to testify against Bushco for war crimes, probably 'escaped' six feet under - compliments of the CIA - those evil fucks all-too-familiar with the fates of los Desaparecidos.
