The same how its handled in Pakistan, the Democratic setup leaves a lot a chance for the culprits to prove their innocence(which they do not have) but during the legal battle, either they die of old age or bribe a way out.
Thats the point democracy. We dont need democracy as defined in the west. Chinese are lucky their system allowed them to get much higher literacy levels than in our countries, did you notice that when the olympic torch was being carried around the west were desparate to get chinese abroad to make anti chinese comments but most chinese were not taken in. Wheras I often see pakistanis and indians take a western position against their country of origin.
