Rio de Janeiro residents protest man's disappearance 2013
Starting in 2008, the Brazilian government began commissioning nearly forty police pacification units (UPP) in over two-hundred of Rio de Janeiro’s shantytowns, known as favelas. This pacification project aimed to maintain security in territories after Rio’s special police unit (BOPE) cleared the communities of gang leaders and drug traffickers who, for decades, controlled the favelas and inspired their violent reputations.
