The tenth and final work, by Helder Ferreira, Elaine Marcial and Joana Alencar, presents the preliminary results of the “Public security in Brazil: a prospective vision” project. In this study, published in June 2015, the authors introduce the future scenarios project developed through workshops held during the previous year, which involved researchers, managers, and specialists in Brazilian public security. The addendum prepared by the authors reveals how much the public security landscape has changed in Brazil since then.
