CB judicial system works, its not a concept unique to Pakistan. Ever heard of Roman Polanski? Absconding criminals at large still have influence but its significantly less. Nawaz Sharif is already convicted though one can argue it was politically motivated, and as far as great Zardari is concerned, the charges against him were dropped last year. Again, let the system work, and then judge its performance. Also, you raised concerns altaf is still running his party; lets hope fresh cases are opened and his henchmen who are assisting him, and the ones that came back to assist him after the NRO are tried.
Perhaps you are right Data , maybe with judiciary being so much in the limelight , this time justice will be served ... well we are keeping our fingers crossed and I do hope judiciary plays its part really strongly and tries them all and gets rid of the NRO's in particular ... inshallah ...
