Unarmed 17-year-old shot in Pittsburgh while running from police
Large crowds of protesters blocked streets in east Pittsburgh, Pennsylvania, on Wednesday, calling for change after an officer shot and killed an unarmed 17-year-old. Cell phone video appears to show Antwon Rose Jr. running from police on Tuesday night. Three gunshots can be heard, but police say the video might not tell the whole story. Susan Koeppen of CBS Pittsburgh station KDKA reports.
