The Brazilian newspaper Folha de Sao Paulo has now reported that one company offering these tours includes a chat with what it calls an "armed soldier". A journalist from the paper, who was posing as a tourist, went on a tour of Rocinha - said to be the largest shanty town in Latin America. While there he was introduced to an armed man belonging to the faction that controls the sale of drugs in the area, who explained he had already spent nine years in jail. The gunman said his principal worries were the police and rival drug gangs. Another man armed with a machine gun told how he worked 12-hour shifts and earned $180 (£90) a week."
