The guy that needs to be Banned and kicked out of Pakistan is Nasim Ashraf - the Chairman of PCB. This Import from USA was obviously brought in thru family friends connections and paid his way up, to take the Chairmanship of the PCB. The PCB also needs to be put on some corrective treatment, they themselves don't follow the rules and discipline, what can they expect from the players.
The most important and note worthy, lucrative, positions that bring you fame and power in Pakistan are either, in Military, the Politics/Industrialists, or Celebrities like the Cricket team and its associated board members. If you want to make a Name in Pakistan, and to be known for something long after you are dead, you should try to get in these Three professions listed above.
This guy apparently has no experience in the World of Cricket, and I think he is a retired Medical Doctor and had his practice in US, after making few Million dollars here, he decided to become famous in Pakistan, and now every once in a while, he shoots some crap on the MVP (Most Valuable Players) of Pakistan, just to exert his own authority. He is also the culprit behind the big loosing streak of Pak, specially in the last World Cup and the 20/20, he has been intimidating Pak team ever since he got his position, no one in the team likes him.
Yes, Shoib Akhtar is not an envy of the Youth, specially after his insane behavior, he needs to be taught a lesson too, but banning alone will not teach him anything, it makes him more rude and pathetic. He needs to be put in some Real Military Boot Camp, deprived of his everyday luxury life and be kept away from chics, cars, booz and all that. Only that can fix him. But he is a free man, and specially now, after the contract with IPL, he would not give a hoot to anything PCB levies on him. He's got it made......
