In this photo taken Nov. 22, 2012, an alleged crack addict, center, reacts as a social worker tries to calm her during a raid to take addicts to a nearby shelter in Rio de Janeiro, Brazil. While some people go meekly, many fight, cry, scream out in desperation in their altered states. Once they're gone, their paltry belongings, ratty mattresses, pans, sweaters, are swept up by a garbage removal company. With a boom in crack use over the past decade, Brazilian authorities are struggling to help such users and stop the drug's spread, sparking a debate over the legality and efficiency of forcibly interning users. Adults can't be forced to stay in treatment, and most leave the shelters within three days. (AP Photo/Felipe Dana)
