I'm not assuming anything with regards to the ball tampering incident, although it is perhaps fair to comment that Hair's offer has increased my doubts about Hair and not the umpire who did not make the offer.

The only bit I feel convinced on is the decision following Pakistan's protest was the correct one. That is based purely on my understanding of the law and a wish that "player protests" do not become a feature of the game even if they have been treated in a manner that is later shown to be wrong. That is not to say that I believe Pakistan might not have good reason to feel aggrieved (or for that matter that I feel convinced that the umpires' decision regarding the ball tampering might not have been founded).
