The Guantanamo Detainees: The Government's Story, Professor Mark Denbeaux et al., Seton Hall Law School, February 7, 2006 [profile report on 517 Guantanamo detainees based on US Department of Defense data]. Excerpt:

This Report is the first effort to provide a more detailed picture of who the Guantanamo detainees are, how they ended up there, and the purported bases for their enemy combatant designation. The data in this Report is based entirely upon the United States Government’s own documents. This Report provides a window into the Government’s success detaining only those that the President has called “the worst of the worst.”
