Gwen Berry, the left-wing activist and hammer thrower who famously protested the national anthem during a competition in June, placed almost dead last in the Olympic final on Tuesday. Berry finished 11th out of 12 competitors, registering a distance of 71.35 meters — over four meters short of a medal. Prior to her Olympic failure, Berry hinted that she might protest her own country on the world stage. “I feel like I’ve earned the right to wear this uniform,” she said after making it through the qualifying round. If given the opportunity, Berry might have turned what should be a moment of personal and national triumph into a political spectacle.
