IF EVER there was a case that cried out for enhanced interrogation techniques, it was the appearance of the Pentagon's former top lawyer in the US Senate.

William "Jim" Haynes II, the man who blessed the use of dogs, hoods and nudity to pry information out of recalcitrant detainees, proved to be a model of evasion himself as he resisted all attempts at inquiry by the Armed Services Committee.

Did he ask a subordinate to get information about harsh questioning techniques?
