Who killed Benazir Bhutto?

We may never know for sure, but it is certainly a good sign that Pakistan is turning to Scotland Yard for investigative help. Pakistani officials quickly blamed Beitullah Mehsud, a Pashtun tribal leader with ties to the Taliban and al Qaeda, but their bungled and conflicting announcements about Bhutto's cause of death have only deepened suspicions in Pakistan and abroad about some kind of cover-up. The U.S. intelligence community is reportedly withholding judgment. British investigators could help clear up some of those questions. Still, with the crime scene immediately swept clean and Bhutto in the ground, the best forensic evidence will probably not be available to them.

It's therefore likely that Bhutto's assassination will join that of former Lebanese PM Rafiq al-Hariri as an "unsolved mystery." (We're now on our third U.N. special investigator in the Hariri case, with very few little to show for it.)
