In recent decades, the global debate on gun control has been prominent, with many countries adopting more restrictive policies. Brazil followed this trend by implementing stringent measures in 2003; however, the presidency of Jair Bolsonaro in 2019 introduced normative changes aimed at facilitating public access to firearms and ammunition. Throughout his term, the legal firearms market doubled, allowing access to weaponry previously restricted to the general public. The analyzed hypothesis suggests that these normative changes, especially those related to the quantity and authorization of acquisition of previously restricted firearms, altered the types of firearms in circulation, strengthening the interaction between legal and illegal markets. Using data from the mandatory firearms re-registration, a total of 962,782 firearms were analyzed. The assessment of the increase in circulation of these firearms in the illegal market was conducted through the analysis of seizures in the states of Rio de Janeiro and São Paulo, revealing a significant growth in seizures of these types of firearms, possibly correlated with the increase in their circulation. Three police investigations were selected to exemplify how the connection between markets intensified, allowing criminals to obtain firearms in the legal market that were previously only accessible through international trafficking or diversion from state agencies.

Good public policies are based on facts and data, and the most effective laws are written when policymakers understand the effects of such laws on a range of outcomes and can weigh the inherent trade-offs. As part of the RAND Gun Policy in America initiative, we conducted rigorous and transparent reviews of what current scientific knowledge could tell the public and policymakers about the true effects of many gun policies that are frequently discussed in state legislatures. Our first review, released in 2018, synthesized the available scientific data from studies published between 2004 and 2016 examining how 13 classes of state-level gun policies affect firearm-related deaths, violent crime, the gun industry, participation in hunting and sport shooting, and other outcomes. In 2020, we released an expanded and updated review, which added five new classes of gun policies and extended the period over which we conducted our literature search to span from 1995 to 2018. In 2023, we incorporated those studies in our updated analyses, drawing new or revised conclusions about the quality of evidence available to support claims about the effects of various policies.
