The body cameras of the three military police officers involved in the incident that resulted in the death of doctor Andréa Marins Dias were not operational and did not record the event. Last year, the Public Defender's Office made 2,500 requests for access to footage from these cameras, but only 1,500 were met, indicating a significant lack of compliance with public accountability. According to the office, 40% of these requests went unanswered, raising serious concerns over transparency and accountability in the use of police body cameras.

In at least 337 instances, the Military Police claimed that body camera footage had been lost, a statistic that represents 13.4% of all requests. Defender Pedro Paulo Gouvêa de Souza expressed concern over these figures, highlighting that each lost video represents a crucial piece of evidence in the criminal justice process. He emphasized that these cases are not just numbers, but they reflect lives affected by the actions of law enforcement, underlining the importance of utilizing such equipment to ensure justice.

The law mandating the use of body cameras by police in the state of Rio de Janeiro was enacted in June 2021, following a controversial police operation in the Jacarezinho favela that resulted in 28 deaths. This implementation aimed at increasing transparency and fostering trust between law enforcement and the communities they serve. However, the ongoing issues with the functionality of these cameras and the significant percentage of unfulfilled footage requests pose clear challenges to the effectiveness of the law, necessitating urgent reforms in police practices and accountability measures.
