My love for Musharraf and what he did with rule of law by letting both Nawaz and Zardari loose is special as I am from Karachi too.
There is no excuse that can justify prolonging the political life of the corrupt elitists as was done by Musharraf. He understood the stakes for the future of Pakistan, he really had a golden chance...But he blinked, looked the other way and then never looked straight from that moment on.
Considering the wealth enjoyed by Musharraf after his retirement despite confiscation of local assets by courts, I won't be surprised if the deal with Nawaz and Zardari involved monetary exchange abroad between the culprits or their foreign guarantors and (in favour of) Musharraf.
This is exactly why I admire the current top brass for not repeating the mistakes of the past, standing for rule of law and setting higher standards of professionalism rather than personal gain, political or otherwise.
Had Musharraf taken this path then Pakistan would have been leaps and bounds ahead instead of being stuck with the same corrupt lot. Let's move on.
Let's make an example out of Mushy in due course along with Zardari and just like Nawaz is facing his fate right now. If Nawaz gets away then it shall all be of no use.
A society can survive with kufr (infidelity), but not injustice.
