Please, Dhoni has not been accused. The report claims a small time bookie claimed to a police officer that dhoni was involved. But there is no prima facie any evidence or leads to follow it up. What the bookie said is hearsay. He did not get Dhoni to fix, he has no evidence of who did.
Comparing such rumor spread by a bookie with the obvious guilt established by a sting operation on your players is intellectual dishonesty. ICC is not going to suspend anyone just because one person makes a claim. That was entire cricket teams can be taken out before a tournament by just making an unverified claim.
I also understand the desperation of some people to claim the world cup was fixed for India to win. The report talks about corrupt practices. So if India was involved, they took money to win matches? But people are giving it a different color because India won, and thats too much to digest even today LOL!
