Deputy Mendonça Filho, the rapporteur for the Public Security PEC in Brazil's Chamber of Deputies, made a case on Tuesday, October 10, for lowering the age of criminal responsibility to 16 years for individuals committing violent crimes. This proposal stands in contrast to the original PEC, which was submitted by President Lula's government to Congress in April 2025 and does not include measures for reducing the age of criminal responsibility. Mendonça Filho's advocacy indicates a shift in the political debate surrounding juvenile crime and public safety in Brazil.

The Public Security PEC seeks to integrate the country's various public security forces, aiming to enhance cooperation among different branches such as the Federal Police and the Highway Police. Additionally, it proposes reforms for the management of Brazil's prison system to address ongoing issues of overcrowding and inefficiency. Mendonça Filho's suggestion to hold a public referendum in 2028 regarding the potential reduction of the age of criminal responsibility emphasizes a commitment to involving the Brazilian populace in significant legislative changes concerning crime and punishment.

Mendonça Filho's stance reflects broader social concerns about crime rates in Brazil, particularly violent crime, and the perception that current laws may not adequately address these challenges. By proposing a consultation, he also highlights the complexities of public opinion on such sensitive issues, potentially setting the stage for a heated debate in the years to come as the nation grapples with the effectiveness and fairness of its criminal justice system.
