I'm guessing that he's referring to the story involving Corey Haim. He did an interview with Nightline a while back and said that pedophilia was Hollywood's number one problem. After the interview a number of former child stars spoke out about the commonality of child sex abuse in Hollywood. It's one of those stories that you don't want to blow out of proportion and paint all of Hollywood with a wide brush, but you certainly don't want to dismiss the issue either.
