Turns out, ABC News's Diane Sawyer isn't going to get that exclusive jailhouse interview with accused murderer Robert Blake after all. On Tuesday, Los Angeles County Sheriff Lee Baca pulled the plug on the Q&A, citing a department policy prohibiting inmates from doing TV chats during ongoing criminal cases. Ironically, Harland Braun, the lawyer who has represented Blake since his wife was killed last year, resigned as the actor's attorney Monday because he was miffed the former Baretta star agreed to talk to Sawyer. There's no word if he'll go back to work for Blake now.
