Just four days before South America's first Summer Olympic Games, there's still widespread fear that Rio is unprepared to stage a global spectacle. There's a crime spree, corruption and shoddy construction of major venues. Water contamination is a threat to the health of swimmers and sailors. And the Russian doping scandal has cast doubt on the integrity of world-class athletics. We hear what all this means for the quality of the competition, the size of the crowds and rules for staging Olympiads of the future.
Is Rio ready for the Olympic Games?
