I caught the This American Life episode where Ira Glass retracts Mike Daisey's Apple expose over the weekend. It was interesting, but I felt like Ira Glass came across as someone who couldn't get over the fact that Mike Daisey lied to him and hurt his feelings.
Both men should have walked away from this story the moment Glass asked to contact Daisey's interpreter. Instead, Glass took Daisey's word for it when he said he couldn't find the translator, and Daisey lied so that the piece could be passed off as actual journalism. I have no idea what was going through the mind of Rob Schmitz, the Shanghai-based reporter who uncovered Daisey's deception, but perhaps he was motivated by a desire to show This American Life what real reporting looks like, and what it really means to fact check.
Anyway, here's a link to Columbia Journalism Review's critique of the episode.
I also like film critic Jim Emerson's take on it.
