Judge cancels Rio Live Earth concert
The Live Earth concerts will be held in cities around the world on July 7

RIO DE JANEIRO (AP) — A judge has canceled a Live Earth concert planned for Saturday in Rio because police said they did not have enough officers to guarantee crowd safety.

Organizers of the free show on Rio's Copacabana Beach said Wednesday they were trying to overturn the order to prevent Latin America from being left out of the worldwide music fest aimed at stopping global warming.
