Photo of Cop Sleeping on the Job in America's Most Violent City Prompts Investigation

Caught napping in Camden, New Jersey

(Reuters) - A photo of a police officer in Camden, New Jersey, apparently asleep in his cruiser has prompted an investigation in the U.S. city with the nation's highest violent crime rate in 2012.

The photo, which shows the uniformed officer wearing sunglasses, head cocked back and mouth agape in the driver's seat, began circulating on Camden-related Facebook pages this week.
