Sports 2012 images: Olympic controversies

South Korea's Shin A-lam cries after a controversy over timing saw her to lose to Britta Heidemann of Germany in the women's epee individual fencing semifinals at the London 2012 Olympic Games at ExCeL on July 30, 2012. The pair tied 5-5 in regular time. According to the rules, Shin would have won if the two had drawn in extra time. But the German launched a last-ditch attack in the final second of the match, which was suspected as being wrongly timed, and was awarded. [Photo/CFP]
