I don't know about the reasons you have but here is another twist, if you can look at it given your expertise.
What if Shireen Mazari & Fawad Chaudhry may have caused more damage to Agencies as compare to Matiullah's arrest? Both of them fools just put pressure on LEAs. Now whatever the update will come, the troll brigade & libtards will use it to their advantage and will try to prove it like LEAs now shaming Government Ministers. Then-after, imagine the propaganda and all the mislead & disinfo through social media. Why don't you think that these ministers have to remain shut for a while and let's the concern department come forward with details and everything. In such situations of suspicion; I don't even believe into Ministers at all. What if some faces are playing double.
Things cannot get clearer just because of our own doing. Look at all this conversation. Everyone has made his/her mind yet you blame the Country or system. We are not letting the audit to happen of things to get clear. How much do you think we are democratic in such practice? example is right in front of you. Had been to myself to understand; I will read thread again and see if we are democratic enough and let the time come to criticize but we are not because we already have made our mind.
