Dipanjan Roy Chaudhury reports for India Today:
It is no secret that Bhutto faced threat from extremist forces including the Taliban. In fact her very return to Pakistan on Oct 18, 2007 was marked by bloodshed when a suicide attack on her motorcade at Karachi killed 140 people mostly her supporters and PPP activists.
Bhutto survived that attack but it was obvious that she was the target.
Subsequently the PPP president did not trust the state apparatus as she thought that it was hand in glove with the Taliban.
