Cheating is a problematical word in sport. Lance Armstrong, Ben Johnson and the East German female athletes, sponsored by Gilette, cheated. On a human level I would have loved to see him walk, but the way football has been going in the last decade, I really can't fault his decision. Sad as it is...
Michael Atherton caught behind at the SCG but held is ground. When the slip cordon and wicketkeeper tried to sledge his unsportsmanlike behaviour, he simply stated 'when in Rome'.
Adam Gilchrist walked and was slated.
Umpires decision. Nowadays you wait.
