It's a sad affair, but I'm afraid that there are so many drugs out there that it gets hard for the sports governing bodies to test for them. There are always new drugs being created, and the drug testers are always one step behind. You get athletes being banned when they have not taken any performance enhancing drugs and athletes taking drugs and getting away with it.

I believe Warne is innocent but you can never be sure. It's a shame to see the best spin bowler for the last 20 years be out of the game for a whole 12 months.
