White collar crime (and the way our countrymen are involved in corruption, payment usually outside the country) is neither easy to trace nor easy to prove in courts, especially when the money is parked in jurisdictions which do not want to cooperate. Otherwise the Supreme Court has done all that it could to facilitate Imran Khan, to the extent of disqualifying a PM. NAB has done all it could, perhaps even doing many things illegally. The Military and ISI have done everything they could, except maybe against PPP with which they seem to be in a deal.
