The Supreme Court of Brazil has decided that all military police in São Paulo must use body cameras during their work.

Impact on Police Operations
Studies have shown that the use of body cameras can significantly reduce incidents of police violence.
Research by the Brazilian Forum on Public Safety revealed a 62.7% decrease in deaths resulting from police interventions in São Paulo, with the majority of this reduction occurring in battalions equipped with body cameras.
It also has the potential to significantly reduce the homicide rates, and lead to higher safety in cities all over Brazil. Removing bribing police officers as a possibility is surely a huge step forward.
Governor Revises His Position on Body Cameras
Governor Tarcísio de Freitas initially opposed the expansion of body cameras but changed his position after reviewing the evidence.
He announced plans to extend the program statewide, acknowledging the benefits for both public safety and officer accountability.

The Ministry of Justice and Public Security has introduced federal rules for using body cameras.
Officers must record specific situations, including personal searches and responses to incidents.
The new standards aim to improve oversight and ensure that cameras operate effectively.

Benefits in Policing
Global studies show that body cameras reduce the use of force and provide clear evidence during investigations.
In São Paulo, pilot programs have already shown a decline in police-related deaths when cameras are used consistently.
Public Support and Future Plans
The mandatory use has gained strong public backing. Advocacy groups and families affected by police violence view this move as a step toward justice.
The São Paulo government is now responsible for ensuring proper use of the devices, training officers, and monitoring compliance.
Mandatory cameras are expected to reduce violence and increase transparency. Other states may soon follow São Paulo’s example to build public trust in law enforcement.
