If the president is so worried that prosecutions of America’s torturers and torture-enablers could feel like a partisan witch hunt, why not turn to a Republican with firsthand experience in being tortured?

John McCain seems like the right man to get to the bottom of this fiasco, although the Senate Armed Services Committee has done a bang-up bipartisan job so far without need for President Obama’s approval. We know that the Arizona senator has taken some heavy shots from opponents of torture for his actions regarding anti-torture legislation, but it cannot be denied that he has painful expertise on the subject. The passion that he has voiced against torture could now serve the nation well in an effort to seek the full truth, and justice, in the present controversy.
