A woman, who was feeling sick and was identified by municipal agents as a suspected crack user, is carried to a municipal vehicle during an operation by Rio de Janeiro's Social Action Secretariat to bring crack addicts to shelters for rehabilitation, near the Parque Uniao slum in Rio de Janeiro November 14, 2012. Municipal agents approached people showing signs of crack abuse during the operation to offer to send them to shelters as part of the efforts by authorities to end crack use in Rio's slums, including nine areas known as Cracolandias or cracklands in the city. The exercise is mainly voluntary, except for suspects who broke the law. REUTERS/Ricardo Moraes (BRAZIL - Tags: CIVIL UNREST CRIME LAW DRUGS SOCIETY HEALTH TPX IMAGES OF THE DAY)
