The Obama administration is considering creating a hybrid military-civilian prison in the United States to hold and try prisoners currently at Guantanamo. The proposal calls for a combined detention and trial facility to be built in an existing US maximum-security prison. The proposed facility would be operated jointly by the Departments of Justice, Defense and Homeland Security. Officials said such a facility could also house prisoners held in indefinite detention. The American Civil Liberties Union said it would oppose such a facility, especially if it included holding some prisoners indefinitely without charge or trial. Jameel Jaffer of the ACLU said, “Closing Guantanamo will be an empty gesture if we just reopen it on shore under a different name.”
