This article analyzes the legal and institutional feasibility of implementing the full police cycle within the Military Police of the State of Amazonas, considering the Brazilian public security model and its impacts on police operational efficiency. Based on a historical and constitutional approach, the study examines the origins of the Brazilian policing system, characterized by the fragmentation of responsibilities between preventive/ostensive policing and judicial investigation, highlighting the limitations of the incomplete police cycle model in addressing contemporary public security demands. The research adopts a qualitative methodology, grounded in a bibliographic review, legislative analysis, and examination of constitutional amendment proposals aimed at reforming Article 144 of the 1988 Federal Constitution. The analysis discusses the main pathways for implementing the full police cycle, taking into account international experiences and different institutional arrangements within the Brazilian federal context. In this scenario, the Military Police of Amazonas stands out due to its territorial capillarity, available personnel, and continuous presence in ostensive policing activities. The study indicates that adopting the full police cycle may contribute to the rationalization of public resources, reduction of institutional rework, and increased responsiveness of the State to police occurrences. However, its implementation requires constitutional amendments, strategic planning, professional training, and the overcoming of institutional resistance. It is concluded that the full police cycle represents a relevant alternative for modernizing the Brazilian public security system, provided that it is implemented gradually, in an integrated manner, and in compliance with the principles of the Democratic Rule of Law.
