Advancing justice: The impact of Brazil’s convict genetic profile identification project after 5 years

This comprehensive study analyzed the implementation and impacts of the Convict Genetic Profile Identification Project in Brazil. By examining semiannual reports from the Integrated Network of DNA Databases (RIBPG) alongside a literature review covering the period from January 2018 to February 2024, the study evaluated the project’s relevance. The project’s primary aim was to enhance DNA databases, thereby fortifying crime prevention and resolution efforts. Notably, the results revealed a substantial increase in genetic profiles of convicted offenders included into the Brazilian National DNA Database (from 2,008 in 2017 to 54,657 in 2019) − a development that aligns with legislative goals. Despite legal and ethical debates, the project demonstrated a positive impact on criminal investigations, with a notable rise in database matches (from 376 in 2017 to 1,418 in 2019). Scientific literature had highlighted the project’s effectiveness in resolving crimes. The project has matured into a well-established process, characterized by continuous insertions and advancements, emphasizing a comprehensive operational framework. Beyond quantitative milestones, it has made qualitative contributions to justice. This collaborative model serves as an example for impactful public policies under Brazil’s Ministry of Justice and Public Security.
