David Cole in the New York Review of Books:
The story of America's descent into torture in the wake of the terrorist attacks of September 11, 2001, has been told now by many writers. Mark Danner, Jane Mayer, and Ron Suskind have written brilliant expositions of the facts, showing how the drive to prevent the next attack led the administration's highest officials to seek ways around the legal restrictions on coercive interrogation of suspects. After the abuses at Abu Ghraib came to light, the military itself commissioned three detailed investigative reports, including highly critical ones by Major General Antonio Taguba and by a panel led by former defense secretary James Schlesinger. Among other factors, they blamed ambiguity in the standards governing interrogation—an ambiguity ultimately attributable to the attempts at evasion directed from the top. Congressional committees have held numerous public hearings into the use of coercive interrogation tactics at both Abu Ghraib and Guantánamo. The Center for Constitutional Rights, the ACLU, and the NYU Center on Law and Security have each published collections of official documents, which effectively indict the government using its own words.
But undoubtedly the most unusual and deeply revealing take on the subject is the work of the British lawyer and law professor Philippe Sands. As Alexis de Tocqueville showed long ago, sometimes it takes the eyes of an outsider to show us ourselves. Sands, a leading international lawyer and a professor at University College London, took it upon himself to conduct his own personal investigation of one aspect of the torture policy—the Army's adoption of coercive tactics to interrogate suspects at Guantánamo.
