"In 2011, significant progress was made in reducing Rio de Janeiro’s legendary, critical crime rates. The centerpiece of this effort is the Favela Pacification Program (FPP) whereby specially recruited and police officers trained in community policing enter Rio’s favelas (slums), expel drug gang members and other armed criminal elements, and establish a permanent presence, called a Unidade de Policia Pacificadora (UPP). Municipal authorities can then enter the favela and safely deliver much needed social services and economic assistance to residents. The long-term goal of the FPP is to integrate the favela residents into mainstream society, a process that is ongoing and currently exceeding expectations." (Quoted from the article)
