Over the preceding 5 days, Australia played India in a cricket match at the Sydney Cricket Ground (SCG) and while Australia won, the best summary I've seen of the 2nd test match is:
Caught Benson, Bowled Bucknor
Who are Benson and Bucknor? The two umpires appointed to adjudicate on decisions throughout the match. The umpires are appointed for the match by the International Cricket Council (ICC) and are from the countries of England and Jamaica respectively.
It is a great shame for any sport when the actions of the umpires and the decisions they make overshadow the talent and endevours of the players on the field. In Australia, football umpires are often lovingly referred to as White maggots. It appears we need to come up with an appropriate term for cricket umpires too.
As is often the case in life, people are prone to speculate about what if. The only conclusion that can be safely drawn, on reflection, is that if any particular decision is/was made is changed then everything that follows must be different. You cannot change individual events in life and expect all the others to be as they were. The joining together of events in space and time is known as the Butterfly Effect, about which a movie was made in 2004. If you haven't seen this movie, I'd recommend making the time to do so.
Stop worrying about the past and focus on the present and future.
