Why won't Zardari allow an autopsy of Benazir's body?

Re: Why won't Zardari allow an autopsy of Benazir's body?

Zardari knows that if Musharraf's govt autopsy the body, they can remove evidence at will.

I think after Musharraf agrees to a UN or international netural investigation - with autopsy being done by neutral experts - the family should allow exhumation and autopsy.
