Im pretty much completely in agreeance with MacGill here, what he said has been taken out of context a little but, all he actually meant was that it gets blown out of proportion and some players are overly sensitive to it.
The crowds are the reasons players earn these 6 and 7 figure sums, without public interest they would be nothing. Unfortunately in life some people arent as respectful as others and they might enjoy getting off their faces and yelling abuse at a player, deal with it, I'd gladly get sworn at and called names by drunk bogans for a million bucks a year as would anybody. Its part and parcel of being an international sportsman, and I know Murali may be more sensitive than others due to the nature of what he's had to go through to clear his action, but he knows its legal, the people who make the rules have deemed it so and the opposition know its legal, so who cares if the moron in row 32 thinks he's a chucker, harden up and play some cricket its what you're paid for.
