I’d say this paragraph pretty well sums up American “terrorist policy” from 9/12/2001 on:
…whatever the truth about the detainee’s role before his capture in 2002, it is receding into the past. So, presumably, is the value of whatever information he possesses.

His assessment of January 2008 — six years after he arrived in Cuba — contended that it was worthwhile to continue to interrogate him, in part because he might know about Mullah Omar’s “possible whereabouts.”
