There is thing called burden of proof & govt of Pakistan has failed to prove anything (btw, I’m not sayting they are innocent). However, we know that GoP, both under NS and Mushrraf, spent millions of rupees hounding them around the world, yet never could prove anything against either BB or Zardari. Also, we know that NS pet judge Malik Qayyum was instructed by him to convict them & conviction was over turned by the SC.
