So how exactly was Benazir Bhutto killed!? (MERGED)

Re: BB's death was not caused by bullets or bomb fragments

She was killed by bullet wounds on the neck. Which were not fired by suicide bomber.
So If Govt. tell ppl that she was killed by a trained sniper and bomber was just a backup. People are going to know that agencies murdered her.
I mean come on its pakistan other then ZAB we are never told who killed who. Zia/liaqat/ and now benazir.
