This terrified boy, caught out alone at night, is about to be shot by Brazilian police officers. Street children are a big problem in many parts of the world, from India to Russia. They are thrown out by their parents, who can't afford to feed them, and must survive alone or in gangs, stealing, begging or prostituting themselves. For years Latin America has been infamous for its death squads that hunt and kill street children. The police officers above shot this boy several times in the chest and left him for dead. He survived. The attack was recorded by a private security camera. Ironically, this boy did have a family to go home to. He wasn't truly a street child. His attempted murder was in August 2010. Afraid of police reprisals, the family, the person in charge of the security camera and the reporter he showed the video to all dithered over reporting the crime. Recently they decided they must report it. The boy and his family are now in a witness protection programme. Five police officers have been arrested and face charges of attempted homicide. It puts today's anti-cuts march in London into perspective.
