A man who identified himself as a police officer points his gun at anti-World Cup protesters blocking a road that leads to the Maracana stadium in Rio de Janeiro, Brazil, Sunday, June 15, 2014. The man told people not come any closer to him, and fired shots into the air which dispersed the crowd. He then continued shooting from a car driven by another person as they left the scene.
