Reforms can always be made to the legal process at Guantanamo, and so this is not a reason to close the facility or to try the detainees in US courts. Moreover, much of the credible and reliable evidence that justifies the continued detention cannot be admitted in US courts for legal reasons, such as the fact that those captured in Afghanistan and elsewhere were not read their Miranda rights on their arrest. Other cases involve evidence that is insufficient for trial but still sufficient to determine that release is an unacceptable security risk. [1] Furthermore, If transferred to U.S. courts, some of the detainees might be freed because of the aggressive interrogation techniques used against them. Mohammed al-Qahtani, the alleged "20th hijacker" in the Sept. 11 plot, was interrogated so severely at Guantanamo Bay that Bush administration officials said he was tortured and did not refer his case for prosecution.
