First of all let investigations get completed before we can conclude that they were really involved..though prima facie evidence does work against them.. Now why doesnot have concrete answer , since only they can give precise answer...it might be greed ,it might be insecurity about how many games they might be able to play or not play..there can be n number of reasons...important thing is cleaning the system and nailing who so ever are involved..i don't mean only this series and only pakistan players..
May be they are attracted towards the money which cricketers in other countries are earning.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
