I agree crime is a crime, but not all crimes are same. I do want to remind you that high treason is the only crime specifically listed in the Constitution & its punishment. All other criminal offenses come under Pakistan criminal penal code.
As for non-performance of politicians, you have to ask where did all these politicians came from? Did they come out of strong political system or did the come out system that has never been allowed to work by the military? Also, keep in mind that regardless of political failings of politicians, the army has no role in politics whatsoever in any civilized nation.
If only people can understand this fact. This abrogation of constitution is the mother of all ills in our country and unless law takes it's course against this mother of all ills in future also an
army generals can always take the same course. The political system which evolves out of these constitutional abrogations is as rotten as the army rule itself.
