You are absolutely right mkdezel, one should not criticize anyone. I had given just my own humble opinion that since the NAB has not yet declared final result after the completion of the whole process so issuing conditional letters is a far fetched idea.
As far as tough time over NAB is concerned, I think that the Chairman has played a very dangerous trick by making this issue public because a debate will start on the working on NAB and he will then respond in increasing the powers of NAB rather than decreasing it through ratification of NAC bill. I consider that it can either back fire or will put him in a very commanding position so LET US PRAY that if his deeds are for saving PAKISTAN from real myth of CORRUPTION then ALLAH may help him and US!
