Police can now pursue suspects across borders with coordination
Casi seis años y medio después de su firma, Brasil promulgó esta semana un acuerdo policial del Mercosur que permite a las fuerzas del orden de Argentina, Brasil, Paraguay y Uruguay perseguir sospechosos más allá de las fronteras nacionales en operaciones coordinadas contra el crimen organizado. El decreto, firmado por el presidente Lula da Silva, responde a una realidad que los mapas nunca pudieron contener: las organizaciones criminales transnacionales que operan con fluidez donde los Estados actúan por separado. El acuerdo aún requiere la ratificación de al menos dos miembros para entrar en vigor, pero marca el inicio de una arquitectura legal que podría redefinir la soberanía compartida en materia de seguridad regional.
- Grupos criminales como el Primeiro Comando da Capital y el Comando Vermelho operan sin fronteras, y los Estados del Mercosur carecían hasta ahora del marco legal para perseguirlos con la misma libertad.
- La triple frontera entre Brasil, Paraguay y Argentina —zona históricamente porosa y difícil de controlar— es el epicentro de la urgencia que impulsó este acuerdo.
- El decreto firmado por Lula da Silva activa un mecanismo que dormía desde diciembre de 2019, convirtiendo un compromiso político en una herramienta operativa concreta.
- Los oficiales podrán cruzar fronteras en persecución de sospechosos, pero deben operar bajo la ley local y la supervisión del país receptor, un equilibrio deliberado entre acción y soberanía.
- El acuerdo no entra en plena vigencia hasta que al menos dos naciones depositen sus instrumentos de ratificación, dejando abierta la pregunta de cuán rápido seguirán los demás.
El gobierno de Brasil promulgó esta semana un acuerdo policial regional del Mercosur que transforma la manera en que las fuerzas del orden pueden actuar en América del Sur. El decreto, firmado por el presidente Luiz Inácio Lula da Silva, habilita a policías de Argentina, Brasil, Paraguay y Uruguay a perseguir sospechosos cruzando fronteras internacionales durante operaciones coordinadas contra el crimen organizado —una facultad que hasta ahora no existía.
El acuerdo había sido firmado en diciembre de 2019 en la ciudad brasileña de Bento Gonçalves, pero permaneció inactivo durante casi seis años y medio, a la espera de ratificación. La adopción formal por parte de Brasil representa un paso decisivo, aunque el texto no entrará en plena vigencia hasta que al menos dos de los cuatro países miembros depositen sus instrumentos de ratificación.
Bajo este marco, un oficial puede continuar una persecución más allá de la frontera siempre que exista comunicación inmediata con las autoridades del país receptor. Cualquier detenido debe ser entregado a las autoridades del territorio donde fue aprehendido, y los agentes deben operar bajo la legislación local. El acuerdo también contempla investigaciones conjuntas, vigilancia transfronteriza e intercambio de inteligencia, tecnologías y programas de formación.
La urgencia detrás del acuerdo es concreta: organizaciones criminales brasileñas como el Primeiro Comando da Capital y el Comando Vermelho operan con soltura a través de las fronteras, movilizando drogas, armas y contrabando. Este mismo mes, Estados Unidos las designó como organizaciones terroristas, subrayando la dimensión del problema. La triple frontera entre Brasil, Paraguay y Argentina —zona históricamente sensible— es el símbolo más visible de esta realidad.
Lo que faltaba no era voluntad, sino arquitectura legal. Este acuerdo la provee. Si los países restantes ratifican con celeridad y si la práctica operativa está a la altura del texto jurídico, son preguntas que el tiempo responderá.
Brazil's government formally enacted a regional police accord on Wednesday that fundamentally reshapes how law enforcement operates across South America's largest trade bloc. The decree, signed by President Luiz Inácio Lula da Silva and published in the official gazette, allows officers from Argentina, Brazil, Paraguay, and Uruguay to pursue suspects across international borders during coordinated operations against organized crime—a power that did not exist before.
The agreement itself was signed nearly six and a half years earlier, in December 2019, in the Brazilian city of Bento Gonçalves. For years it sat dormant, awaiting ratification. Brazil's formal adoption this week represents a significant step, though the accord will not take full effect until at least two of the four member nations deposit their instruments of ratification. The machinery is now in motion.
Under the framework, police officers can continue pursuing a suspect even after that person crosses a border, provided there is immediate communication and coordination with authorities on the other side. An officer may enter another country's territory to make an arrest, but must operate under local law and under the supervision of that country's competent authorities. Officers and vehicles must be properly identified. Anyone detained is handed over to the authorities of the nation where they were apprehended. The agreement also establishes mechanisms for joint investigations, coordinated operations, cross-border surveillance, and the exchange of information, methodologies, technologies, and training programs.
Requests for cooperation can be approved in full or in part, or even delayed if they might interfere with investigations already underway. The language is careful, designed to preserve sovereignty while enabling action. The accord specifically addresses the triple frontier region where Brazil, Paraguay, and Argentina meet—a zone long considered sensitive and difficult to police.
Brazilian authorities view this integration of security systems as essential. The country has grown increasingly concerned about criminal organizations that operate seamlessly across borders, moving drugs, weapons, and contraband with little regard for the lines on a map. Two Brazilian groups in particular—Primeiro Comando da Capital and Comando Vermelho—have drawn international attention. The United States designated both as terrorist organizations just this month, a designation that underscores the scale of the problem.
Narcotraficking, weapons smuggling, contraband, and transnational organized crime do not respect borders. The police forces of these four nations have long understood this. What they lacked was the legal architecture to respond in kind. This agreement provides it. Whether the remaining countries move quickly to ratify, and whether the operational reality matches the legal framework, remains to be seen. But the foundation is now in place for a fundamentally different approach to regional security.

The Hearth Conversation Another angle on the story
Why did it take six and a half years for Brazil to sign off on something all four countries agreed to in 2019?
Domestic politics moves slowly, and security agreements require careful legal review. There's also the question of whether the political will was there. A lot can change in six years.
What actually changes on the ground when this takes effect?
A Brazilian officer pursuing a drug trafficker can now legally cross into Paraguay or Argentina and make the arrest, rather than having to stop at the border and hand off to local police. That sounds simple, but it's a significant shift in sovereignty.
Doesn't that raise concerns about one country's police operating in another?
Absolutely. That's why the agreement requires immediate coordination with local authorities and says officers must follow local law. It's a balance—enabling pursuit while maintaining oversight.
You mentioned the triple frontier. Why is that area so important?
It's where three countries meet, which makes it ideal for criminals. They can move contraband or people across borders in minutes. It's been a blind spot for law enforcement for decades.
The U.S. just labeled two Brazilian gangs as terrorist organizations. Is that why this is happening now?
It's part of the context. International pressure, rising violence, the sense that the old approach isn't working. This agreement is a response to that reality.
What happens if one country doesn't ratify?
The agreement still exists, but it won't be fully operational. You need at least two countries to deposit ratification for it to take effect. So far only Brazil has done so.
