David Kelly was a specialist doing his job to a high standard, who tried to stand against the tide of the Iraq War. To his logical mind, Britain was being sent to war to remove WMD from Iraq which he knew were not there. He tried to do something to stop the war. The people in power had decided to get the war going regardless, and anyone and anything that stood in their way would be eliminated. Kelly paid the price.
Darrell Hair, like Kelly, is a specialist doing his job, and he's also tried to stand against the tide. Umpiring to him is about following the rules and applying them to the circumstances, as does a scientist like David Kelly. Kelly saw that the information he was passing to others was being misapplied. Hair sees that his decisions to apply the rules of the game of cricket are being attacked.
India and Pakistan are angry that Britain and Australia control the game, as in money terms cricket is far bigger in the sub-continent. They are challenging the duopoly, and Britain and Australia are trying to hold on. There is huge money in cricket especially in betting. What's a little ball tampering got to do with it, when millions are riding on the result?
Kelly stood up against the might of The Pentagon. Hair is standing against a wall of money, as he's tried to preserve the standards of cricket - the game he loves.
Like Kelly, he knows that the forces he's standing against are very powerful, and he's looking for a way out. Like Saddam and Iraq, cricket looks doomed. For evil to triumph.......etc
