Rio de Janeiro’s Pacification Police Units (UPP) are celebrating their fifth year in 2013. They do so with generally positive approval ratings from the media and society as a whole. A recent study by Instituto Data Favela indicates that 75% of favelas inhabitants approve of the UPPs. Notwithstanding major crises and criticism, the UPP constitute the single most important public security initiative in the state. And yet the persistent informality of the UPP may eventually undermine its sustainability. (See also: Rio slum pacification police accused of torture, murder)
An average of five people were killed by police every day in Brazil last year, according to an annual security report, revealing an entrenched culture of violence within the country's security forces. Brazil's Forum of Public Security joined forces with US non-governmental organization (NGO) Open Society Foundations to conduct an in-depth study of police killings as part of its annual report, concluding that the country's security forces are beset by a "culture of violence."
