RIO DE JANEIRO, BRAZIL - OCTOBER 06: Soldiers prepare for a 'pacification' operation in the nearby favela complex of Lins de Vasconcelos, in the North Zone, on October 6, 2013 in Rio de Janeiro, Brazil. The favela complex, or shanty town, was previously controlled by drug traffickers and will now be occupied by the city's 35th UPP or 'Police Pacification Unit'. The favela pacifications are occurring amid Rio de Janeiro's efforts to improve security ahead of the 2014 FIFA World Cup and 2016 Olympic Games. (Photo by Mario Tama/Getty Images)
