The "take-over" of Rocinha, one of Rio de Janeiro’s largest favelas, by heavily armed police and military units was seen by some as a media spectacle and by others as part of a successful strategy of regaining state control over an area ruled by armed drug gangs. Less than three hours after 3,000 police and soldiers occupied the favela or in the south of the city, Rio de Janeiro state Secretary of Public Security José Mariano Beltrame announced the "recovery of the territory" by the state.
Four decades after Washington declared its "war on drugs" and began to spread the doctrine south of the U.S. border, the government of the Brazilian state of Rio de Janeiro decided to shift away from that approach towards a strategy focused on community policing. The new focus has already produced results in some of the city’s favelas or shanty towns, which were long off-limits to outsiders, including police. The process began in 2009 with the installation of "Police Pacification Units" (UPPs) in the favelas.
