How could you say that NAB was transparent during IK's tenure? It is just so much baloney when you try to convince me that a corrupt institution which was being handled by army generals during IK's tenure (As per IK himself that NAB was run by army) cannot be corrupt and could not have been used against the political opponents of IK.
Again, it doesn't matter who started the cases, they were all political motivated cases and IK kept them on the table. Same is true during this time with PMLN. These cases under NAB are all political motivated and always will be.
Let me Jag your memory about NAB head Javed Iqbal. He was the head of NAB and his corruption stories was on everyone's fingertips. Not only that he was financially corrupt, but he was also morally corrupt as well. IK tolerated him and used him against the opposition. If IK was such an angel, he should have gotten rid of him at the first time.
I should show you the detail video of head of the NAB during IK tenure. See how he wanted to wash women and purify them with his saliva. And that is the credibility of NAB during IK's tenure.
