RIO DE JANEIRO, BRAZIL - MARCH 21: Military Police (PM) conduct an operation in the 'pacified' Complexo do Alemao 'favela' community following a shootout earlier in the day on March 21, 2015 in Rio de Janeiro, Brazil. The complex of favelas has suffered numerous shootouts recently. The government recently created a commission with the objective to increase social projects in communities such as Complexo do Alemao that have a Pacifying Police Unit (UPP). The new aim acknowledges that the communities, many of which remain plagued by violence and other issues, cannot solely be ?pacified? by police operations.
