Anyone who did not see this coming is obviously deluded about Pakistani politics.
In our entire history, with five military supported & direct military takeovers (Iskander, Ayub, Yahya, Zia and Musharraf's) which have involved countless other civilians including members of judiciary, if only one man is held accountable to answer for all of these past sins and is now to be made an example of and on top of that he happens to come from a minority ethnic group then obviously these questions will be raised. This was the case with ZAB's tainted trial and will be the case with Musharraf.
This is something that NS should have understood before rolling the dice. The perception is that this is a majority ethnicity based government, with a former CJP from a majority ethnic group egging this issue forth and the only one on the receiving end is from a minority ethnic group. I understand that some part of the constitution was held in abeyance, but the selective judicial and political activism against only the former Army Chief purposely lets off all others. This is where the patent unfairness of the whole process comes up.
The fact that the CoAS is not being tried under the PAA is another problem that is being looked upon as a solid case of victimization and vendetta that is being sponsored out of the PM house and the former CJP's camp.
If the assumption is that only bengalis and baloch had the right to talk up their resentment and nobody else should, then we have a thing or two coming our way because by their very nature, minorities are always sensitive to how they are treated and will be vocal. Our option is to either discount it, as many above are, and let it fester, or ensure fairness in all our proceedings.
On the point of victimization, why is it that only Musharraf, as the President and CoAS, was held up on cases such as Lal Masjid, Bugti's death and BB's assassination when he has immunity from it? If these idiots carry on with such victimization then every single leader of Pakistan will be dragged into the courts in the future. What of the Taliban supporters sitting in the FATA receiving drone attacks? What if they open up cases against NS for allowing this to go on? What then? Where do you draw the line to prevent the state from becoming completely paralyzed because everyone from the President down to the secretary are scared about signing off on things that lead to punitive action against troublemakers?
