Who Killed Benazir Bhutto? [merged]

could it be JI that did it?

Jamat was not happy with Benazir for not boycotting the election. Qazi was left out and did not want elections to go ahead without him but PPP's paarticipation had legitimatized the elections plus he wanted to destabilize Musharaf and with this he has achieved all that. Is it also a possible scenario? or was it the Butler that did it?
