Violence against women is not something new, but rooted in the historical-cultural system of female subordination, with its protection addressed in detail in the Maria da Penha Law. This law was created to also protect victims of domestic violence, the focus of this article, whether they are victims of psychological, physical, property or moral violence. Thus, this article seeks to highlight the importance and impacts of police activity in protecting women, highlighting the Maria da Penha Patrol, which is a police patrol created to monitor victims, their protective measures and necessary follow-up after a complaint. With this, the article highlights the importance of reporting as a duty of all people, in addition to demonstrating the difficulties faced by the police in implementing protective measures and the insensitivity of approaches, highlighting the importance of community involvement. The slowness of the judiciary allowing punishments to expire brings insecurity to women who avoid reporting. As a result, research shows an increase in the number of femicides, and more policies should be created for campaigns to encourage reporting. To this end, the methodology used was secondary bibliographic research of academic articles and books.
