well, misplaced courage is hardly worth congratulations, esp. when it involves ruining people's careers and lives. If not, we should congratulate HItler too for being able to stand up for his convictions and beliefts about the Jews....
The thing is, it is an admirable quality when your convictions are right but when it isn't, you just end up looking like an ass. Murali did chuck under the old rules and I suppose in a way, Hair calling him made ICC look up at the whole issue with some ground-breaking results... But it could have so easily gone the other way and Murali could have been absolutely destroyed and the world would have never known that he wasn't doing anything that every other bowler wasn't doing. We would have lost one of the greatest bowlers of all time, heck one of the greatest cricketers of all time..... So, I am sorry, but I don't really have too many sympathies with Hair on this issue. And the way he came out in his book gets me to think that he did seem to have a personal agenda vis-a-vis Murali.
