The 2nd Technical Meeting of the National Network of Specialized Units for Combating Criminal Organizations (Renorcrim), held in Brasília, brought together representatives from state civil police forces across the country, the Federal Police, the Ministry of Justice, and institutions within the justice system to discuss integrated strategies to tackle organized crime. The program included roundtables, workshops, and discussions on new investigative methodologies, best practices, and challenges faced by security forces. At the meeting, Joana Monteiro, Director of Leme, worked alongside researcher Ana Paula Pellegrino and Project Leader Ramón Chaves in developing conceptual definitions of violent criminal organizations, territorial control, and criminal structures, based on applied research conducted with the event’s participants.
