Partly Facetious: why can't NRO apply to arrest warrants?

"So is an MNA automatically security cleared?"
"I am not sure - that's a tough one."
"Well, considering that there are some outstanding arrest warrants against some MNAs and MPAs I would imagine that being an MNA or MPA doesn't automatically imply that you are security cleared."
"What? There are still some with outstanding arrest warrants! My question is: why hasn't the National Reconciliation Ordinance been applied to these poor souls? If the others not only can benefit from past, shall we say indiscretions, as well as get a clean slate to start again then why can't these poor jokers with outstanding arrest warrants?"
"The NRO appears to be precisely what a priest does, right? I mean it absolves the sinner from all past sins." "Except the NRO is not in the eyes of God but in the eyes of the Pakistani President, only the current one I would think."
"Don't be facetious."
"Anyway give me some names."
"The former head of the Punjab Bank, and, if he turns state witness, then the Chaudhrys of Gujrat are going to be next in line. Then there is the former Housing Minister, Safwanullah."
"It can't be Safwanullah."
"Why?"
"Apparently all files that may have shown some, shall we say irregularities, are kind of missing. No one knows where they are or even if they are in existence any more."
"See we need to have all this information on a computer."
"And you think that computer files can't be deleted?"
"Yes, they can."
"And computer files can also be hacked."
"Right, they can also be hacked by members of the public."
"Ah yes, so danger all around."
"Indeed so better to just have it on hard copy which can go missing."
