IOC bans Russia from 2018 Winter Olympics

The IOC (International Olympic Committee) bans Russia from participating 2018 Winter Olympic Games that would have placed in Pyeongchang.

All began when the director of Russia's anti-doping investigator, doctor Grigory Rodchenkov, alleged that the country has a programme of doping and revealed that he had created substances to enhance athlete's performances and switched urine samples to avoid detection. The Wada (The World Anti Doping Agency) to look into those allegations enlisted the services of a law professor and a sports lawyer, Richard McLaren. McLaren concluded that 1.000 athletes across 30 sports benefitted from the doping between 2012 and 2015. Wada obtained a Russian laboratory database which it corroborated McLaren's conclusions.

IOC's president, Thomas Bach after 17 months of investigations came to the decision  to suspend The Russian Olympic Committee. Whatever, the IOC will invite Russian clean athletes to compete in February under the name 'Olympic Athlete from Russia' (OAR) and with a neutral flag.

OPINION:
I think that doping controls have to be more efficient. Nowadays the science has advanced and new technics of hides doping had appeared. In my opinion, if you want to win a competition, you have to do it honestly and without cheating, otherwise the merit of winning isn't real.
