Christopher Paul's case is different from the cases circulating out of the Guantanamo Bay facility as he is a US citizen. Jose Padilla, another US citizen, was originally held without charge at a military brig. After pressure mounted against the Bush administration, notably from the review of his habeas claims, he was transferred to a civilian detention facility in Florida and formally charged. Five years after his detention, a federal court is reviewing potential jurors. Padilla's lawyers are claiming the "dirty bomber" stigma associated with Padilla will make it difficult to find prospective jurors. Padilla also claims he was systematically tortured while in military custody and suffers from a lack of mental competency as a result.
John Walker Lindh, the "American Taliban", was captured during the prison uprising in Mazer-e-Shariff, Afghanistan. The first US combat casualty in Afghanistan occurred in the Mazer-e-Shariff conflict, where CIA officer, John Spann, was killed by the prisoners there. Following the nine-month sentence given to the Australian, David Hicks, for war crimes, Lindh's family had pleaded for leniency from his 20-year sentence. Lindh has recently been transferred to the Supermax facility in Colorado.
Information on Hicks and other background have been widely covered on this site.
