Of the 775 prisoners who have been held at Guantanamo Bay at one time or another since 2001, about 525 were released without charge, and two have been convicted of offences.
Australian David Hicks pleaded guilty in March 2007 to providing support for terrorism and was sent back to his home country to serve the remaining nine months of a seven-year sentence, while Salim Hamdan, Osama bin Laden's one-time chauffeur, was found guilty last August of the same crime and sentenced to a further five months in prison on top of time served.
So goes the war on terrorism.
