A couple of points
1. There is no similarity between the Afridi disgrace and Inzy's 'run out' except that they HAPPENED to be in the same test match - same day.. So I dont understand why they have to be discussed in conjunction. Neither is a justification for the other even if they had happened in the reverse order !
2. The 'run out' decision was a shocker without doubt. Two field umpires and a third umpire seemed , by inference, unaware of the clear point of law. There was no question of interpretation whatsoever.
Its also a fact that almost all the commentators, I suspect most, if not all, the fielders and Inzemam himself appeared ignorant about it.
I wonder how many who argue so passionately here now were aware of it. Sure some were but how many. At least this ignorant undersigned wasn't.
This does not justify umpires ignorance, it just puts another fact in perspective.
No one had any doubts about what Afridi did, inside the ground or anywhere else in the cricketing world, the umpires, the players, the fans, Afridi himself - you name them.
Thats another difference between the two incidents.
