In an AP article entitled, "Militants, Bhutto Aides Allege Cover-Up" it is reported that:
Democratic presidential candidate Hillary Rodham Clinton called for an independent, international investigation into Bhutto's death — perhaps by the United Nations — saying Friday there was "no reason to trust the Pakistani government."
I can think of another event that requires an independent, international investigation because there's no reason to trust the American Government.
Can you guess what that event is? I know that you can.
