As of Monday, the IOC has banned 19 Russian athletes and annulled 12 medals since it began two separate anti-doping investigations.
One of the Russian scientists kept ultra-detailed diaries of the state run doping program. He described the room where they had clean urine to get past the IOC testing at Sochi. In his diaries, the scientist was complaining that the clean urine arrived unsorted. He had to sort them alphabetically and by sport.
