'Gitmo use of tortured evidence forced me to resign' - Ex-Prosecutor

Lawyers defending Guantanamo detainees say they are being persistently silenced inside military tribunals, with any mention of alleged torture in the prison forbidden.

That's as pre-trial hearings for five men charged over 9/11 are set to start this week, while attorneys claim legal restrictions make proper defence impossible.

Colonel Morris Davis, the former Chief Prosecutor at Guantanamo Bay says the U.S. has missed its opportunity to end the Guantanamo controversy while winning public support.
