Turning point in Benazir Bhutto’s case

It was said that Benazir Bhutto was shot dead. But now a turning point in her case. Scotland Yard detectives said Bhutto died of a blast. It seems that there was a head injury on Bhutto’s head and the only source for such an injury is a bomb blast. As no autopsy was conducted, Scotland Yard detectives cannot come for a decision and they cannot predict what might have happened. But PPP is refusing Scotland Yard’s statement. They are telling that she was shot dead by someone in the crowd. PPP doubt that some sort of sophisticated weapons were used to kill Bhutto. PPP is telling that Pakistan government is trying to deviate the case by announcing that she died of a blast. PPP wants a UN probe in this case which is strongly objected by Pakistan president. In addition to this one of the television channels in Pakistan aired another video evidence of Bhutto’s death. I don’t know why an autopsy was not conducted after her death. An autopsy would have cleared all kind of mysteries in her death.
