Crestfallen faces, elated cheers and floods of tears are part and parcel of Olympic judging. But controversy erupted last night over the ladies’ figure skating gold medal, when Russian Adelina Sotnikova beat favorite Yuna Kim, of South Korea, for the coveted prize. Kim skated cleanly and was expected to win. Replacement judges on the panel from Ukraine and Russia led to questions over Russian-favored judging. Others, however, dismissed cries of injustice, saying it came down to a technicality: Sotnikova’s routine was simply harder. Testing judges’ mettle, it seems, should be an Olympic event all on its own.
