Waiting for the wipeout: Photographer Liu Tao snapped this shot in China's Xiamen city as a cyclist hit a submerged pothole. Now he's facing fierce criticism for lying in wait for a hapless cyclist to hit the hole. It raises the age-old photojournalistic question: is it better to capture the suffering for the world to see or put down your camera to help a single person. "I just knew that the city government has paved the pit, and without my pictures, the pit would not be noticed by the government, and there would perhaps be more people falling over," says Liu.
