Definition: The quarantine and stay-at-home measures implemented by most governments significantly impacted the volume and distribution of crime, and already, a body of literature exists that focuses on the effects of lockdown on crime. However, the effects of lockdown on firearm violence have yet to be studied. Within this context, this study analyzes reports of gunshots in Mexico City registered on Twitter from October 2018 to 2019 (pre-COVID-19) and from October 2019 to 2020 (during COVID-19), using a combination of spatial (nearest neighbor ratio, Ripley’s K function and kernel estimation) and non-spatial (Fisher’s exact test) methods. The results indicate a spatial concentration of gunshot reports in Mexico City and a reduction in frequency of reports during the pandemic. While they show no change in the overall concentration of gunshots during lockdown, they do indicate an expansion in the patterns of spatial intensity (moving from the west to the center of the city). One possible explanation is the capacity of possible victims of firearm crimes in certain municipalities to comply with lockdown measures and thus avoid exposure to such crimes.

Definition: In Brazil, one of the most well deemed state-level programs in the prevention of homicides is the so-called Pacto pela Vida (A Pact for Life), executed in many northern regions of the country. The Pact for Life program, one of the most successful state-level projects to reduce the occurrences of homicides and other violent crimes, had its contribution by integrating the public policy of security with the Judicial Power, Legislative Power, municipalities, state and federal government. The value added by this integration has been fundamental for the fact police cycle is not unitary, meaning that the police that arrive at the crime scene are not the same one that investigates.
