I've never crosslinked to a comment before, but this one deserves it. Like a close reading of the Taguba report, the timeline just does not support the Rumsfeld claim that this abuse is not systemic. Nor can I really see Rumsfeld's distinction between 'abuse' and torture'.
It seems to me that treatment ending in death or forcible sodomy amounts to torture in most books. Evidently this true of the Pentagon. Certainly they're putting a lot of effort into covering their collective arse.
Read the timeline.
