According to an interview Benazir Bhutto had with a reporter before she was assassinated Bhutto claims that Bin Ladden was murdered by a man in the

I think someone put forth the possibility of it being a 'slip of the tongue' during the interview. Not sure where it stands now, but I see there are
2 pages of discussion.
