"The image that will stay with me long after the last competitor leaves Rio this week is a decidedly un-Olympic one. Caster Semenya, the women’s 800m gold medallist, extends her arms to fellow competitors Melissa Bishop of Canada and Lynsey Sharp of Great Britain. Sharp, who came in sixth, holds a tearful Bishop, who took fourth, in a tight embrace. Rather than respond to Semenya they remain in their embrace ignoring her. The photo was a sad endnote to one of the most vitriolic media and social media uproars I can recall, one in which the athletes were the casualties. And the International Association of Athletics Federations (IAAF) did nothing to quell it."
