So this is just my speculation and I am human. Asif Ali Zerdari might not be the actual murderer. But this is sure that he knew, and he could easily apprehend the murderers of his wife. And after the murder of Benazir, all Benazir loyalists in ppp got sidelined within few months. So yeah, he is neither very innocent too. But what about bilawal, doesn't he love his mom? I am Amazed.
But it really doesn't matter who murdered Benazir. Benazir herself knew of many murders which were done by his close allies. May be, many murders also happened on her direct orders. She never got apprehended for such crimes, and neither her allies. And then we saw a countless murders in Pakistan, where culprits were known. Many rape cases where rapists were known, got never apprehended.
I mean, it's all jungle law.
Who murdered Benazir, Fatimah Jinnah, Liaqat Ali Khan, Quid e Azam, doesn't really matter. We hate each other, just like dogs, and so we got the lives of stray dogs.
We deserved that.
