If so, you might want to use this interview of Jon Yoo in class, courtesy of the Jon Stewart Show:

Part I http://www.thedailyshow.com/watch/mon-january-11-2010/john-yoo-pt–1

Part II  http://www.thedailyshow.com/watch/mon-january-11-2010/john-yoo-pt–2

While Yoo is largely there to promote his book, the interview offers students some insight into Yoo’s perspective on the lawyer’s role in delivering competent advice.  It sparked good class discussion when I used it this week.
