The window of a taxi is hit by a bullet as Reuters' photographer Paulo Whitaker was injured during an operation at Vila Cruzeiro slum in Rio de Janeiro November 26, 2010. A wave of violence began on Sunday with attacks on police stations and burning of vehicles, actions Rio's top security official said were ordered by imprisoned gang members. Authorities say the attacks are a protest by traffickers after being forced from their turf by police occupations of more than a dozen slums in the past two years.
