In the Rio shantytown of Rocinha, which overlooks a luxury tourist area, drug trafficking and increasing violence have resulted in numerous deaths and a request by Public Security Secretary Anthony Garotinho for troops to aid in the war against drugs. Constant conflicts have occured, the latest when "Lulu," a notorious trafficker was killed in a standoff with the police. Meanwhile, the violence and increased police presence has paralyzed local businesses, once patronized by tourists. Critics have argued that the only reason for such a reaction is the proximity to tourist areas, which recently prompted the suggestion to ring Rocinha and another slum with a 10 foot wall separating the slums from the tourist areas.
