“What we are looking at is a series of show trials by the Bush administration that are really devoid of any due process considerations,” said Vincent Warren, the executive director head of Centre for Constitutional Rights, which represents many Guantanamo detainees. “Rather than playing politics the Bush administration should be seeking speedy and fair trials,” he said. “These are trials that are going to be based on torture as confessions as well as secret evidence. There is no way that this can be said to be fair especially as the death penalty could be an outcome.”
