Bhutto Said Bin Laden Was Murdered

This video has caused quite a stir recently. It comes to you courtesy of YouTube and it features David Frost interviewing the late Benazir Bhutto in November. At the 2:15 mark of the tape she references a man who she said murdered Usama Bin Laden. This statement has conspiracy theorists saying that the reason why she was killed was for leaking this information out. I'm not sure what to make of it. What say you? I don't buy into conspiracy theories, but the issue to me is why would she make this statement.
