^ All of them were prosecuted, except the Chaudhries (their loans were forgiven by Shauky). NS got convicted on corruption, Altaf got convicted for murder, Zardari though not convicted (thanks to mush) but spent like 2/3rd of his life in jail.
Now in all fairness its baba-jee's turn, for his kartoots during the course of 8 years.
Those 'prosecutions' barely resulted in any fruit. Zardari still owns all his billions looted, Nawaz Sharif spent his jail time in Mecca/Medina and still owns all his looted billions, Altaf never saw the jail.... so the justice is not really served yet!
