Questions have been raised over the judges' decision to award Russia's Adelina Sotnikova the gold medal in women's singles figure skating over Yuna Kim of South Korea at the Sochi Games. Critics note that one of the judges had been suspended for a year for trying to fix an event at the Winter Olympics 16 years ago and that another is married to the head of the Russian figure skating federation. Now, nearly 2 million people have signed a Change.org petition demanding an open investigation into the judging of the event. Take a look at the biggest Olympic scandals of all time.
