Ayaz Ameer saheb, your conundrum is why Khursheed Shah, Nawaz Shareef and others are not understanding the dangers that system could derail. The answer can be given with the saying: Ye wo haddi hai jo na nigle chain na ugle!
They are all crooks and they know they have committed too much corruption which can be proven very easily. Why would the take the action needed when they know it would be against themselves? They should not be the decision makers for the nation and must be apprehended immediately. I say let the army take over and cleanse out the country from these criminals.
