Latin America’s Shift Toward Military-Led Public Security Sparks Human-Rights Concerns

Governments across Latin America are increasingly assigning armed forces to policing and prison duties, a strategy that raises doubts about its durability and impact on civil liberties.

The practice of deploying the military for internal security has spread throughout Latin America, with Ecuador, Mexico and El Salvador using troops for street patrols, prison management and prolonged states of emergency in response to surging organized crime. Observers note that these deployments frequently accompany increases in violence, a consolidation of political power within the armed forces, and recurring accusations of human-rights abuses.

In contrast, Chile and Argentina have shown stronger institutional resistance to militarizing police functions, and Costa Rica continues to rely on civilian agencies and financial intelligence despite lacking an army. In Peru, human-rights advocates such as Tania Pariona argue that soldiers are not trained for policing, risk disproportionate force, and that lasting crime reduction requires intelligence, specialized prosecutors and stronger police forces. Historical memories of past internal conflicts, which caused tens of thousands of deaths, intensify sensitivity to expanding the military’s domestic role.
