Matt Doig was the assistant managing editor of investigations for the L.A. Times when Paul Pringle pursued his story about disgraced USC medical school dean Dr. Carmen Puliafito. Doig takes issue with some of the assertions in Pringle’s recent book “Bad City,” and wrote about them several weeks ago in a Medium post entitled “Sex, Meth, Lies and Journalism.” Last week on the California Sun Podcast, we spoke with Pringle about the evolution of his story and his interactions with Times editors. We felt it was worthwhile to give Doig an opportunity to tell his side of the story.
