Yes Yes, Pakistani umpires were the ones umpiring all over the world every time Wasim/Waqar were playing. Not to forget the fact that It was the great Pakistani cricketer Imran Khan who was the biggest supporter of Neutral Umpires.

Crowe is no paragon of virtue, The fact that he himself as the captain of his team allowed one of his players to cheat makes it even harder for me to take Mr. Crowe seriously on the issue.
I have thought about it long enough and It was not only in Pakistan they were getting the movement, they got it in England too and perhaps at other places as well. Not to forget Reverse swing is a pretty common and accepted these days. How much it swings is based on individual talents and there isn't any doubt that Wasim/Waqar were miles ahead in terms of talent compared to the bowlers of today who have success with reverse swing.
Lastly if you are going to accuse Wasim/Waqar of something please do so, but dont hide behind the mask of fairness, because you are not.
