Major surprise (not)... The IOC has bottled it and there is no blanket ban for Russian athletes, only those previously sanctioned... http://www.bbc.co.uk/sport/olympics/36878983 I bet Putin has fallen off his horse laughing...
I guess it would be difficult to prove re individual athletes post-fact, even if it can be shown it was endemic in the Russian team. There are knock on effects too, where clean athletes are pushed out of the top spots by the drug takers, and thus lose funding from their country for later years.
