Oh those crazy Russians. I have to say it is interesting that it always seems to be some of the same countries that are being caught. You know everyone is doing it, so why are the focusing so specifically on the Russians. I can't imagine the havoc it would cause if the US were banned at some point... The IOC would probably loose too much money to ever do that though.
They need to get tough with everyone otherwise Athletics as a sport is dead. I don't think it can recover now as it has just been left to carry on too long.
