Crucially, the files also contain detailed explanations of the supposed intelligence used to justify the prisoners' detention. For many readers, these will be the most fascinating sections of the documents, as they seem to offer an extraordinary insight into the workings of US intelligence, but although many of the documents appear to promise proof of prisoners' association with al-Qaeda or other terrorist organizations, extreme caution is required.
The documents draw on the testimony of witnesses -- in most cases, the prisoners' fellow prisoners -- whose words are unreliable, either because they were subjected to torture or other forms of coercion (sometimes not in Guantánamo, but in secret prisons run by the CIA), or because they provided false statements to secure better treatment in Guantánamo.
