The Obama administration is preparing an executive order that would formalize indefinite detention without trial for some detainees at the U.S. military prison at Guantanamo Bay, Cuba ..., U.S. officials said. Some civil liberties groups oppose any form of indefinite detention. Indefinite detention without charge or trial is wrong, whether it comes from Congress or the president's pen," said Laura W. Murphy, director of the American Civil Liberties Union's Washington legislative office. "Our Constitution requires that we charge and prosecute people who are accused of crimes. You cannot sell an indefinite detention scheme by attaching a few due-process baubles and expect that to restore the rule of law. That is bad for America and is not the form of justice we want other nations to emulate." Legislation supported by some Republicans ... would create a system of indefinite detention not only for some Guantanamo detainees but also for future terrorism suspects seized overseas.
