The disproportional rise in organised crime in Latin America, in terms of the plurality of demonstrations and the seriousness of their impact, has led to a unique erosion of security, peaceful coexistence and social welfare, while the fundamental principles of democracy have broken down, fundamental rights are being violated and the economic and financial system is being spread by criminal law. Faced with this extremely serious situation, many Latin American governments have used the beginning of their armed forces to counter the criminal threat. These, as part of their new powers, have focused on the strategic use of intelligence capacities in the fight against organised crime. This decision has opened a significant debate on the appropriateness not only of the use of the military for this task – outside police forces – but also of involving military personnel in intelligence work within the national territory with operational autonomy, disconnected from the respective national intelligence services, with all the prolegations that such intervention may entail in operational terms and in terms of democratic quality, and respect for the social and democratic constitutional state of law. Abstract The excessive growth of organised crime in Latin America, in terms of the plurality of manifestations and the seriousness of their impact, has led to a singular erosion of security, serious coexistence and social well-being, while at the same time breaching the consubstantial principles of democracy, fundamental rights and the criminal contagion of the economic and financial system. Made with this situation of extreme gravity, many Latin American governments have resorted to the use of their Armed Forces to counter the criminal threat. And these, within their novel Attributions, have opted for the strategic use of intelligence capabilities in the fight against organised crime. Decision that has opened a relevant debate on the adequacy, not only of the collection to the military establishment for this purpose – from the police forces -, but the delicate task of invasive military personnel in intelligence work within the national territory with operational autonomy, held from the respective national intelligence services, with all the prolegomena that this intervention can intervene in operational terms and of democratic quality, and respect for the constitutional social and democratic state of law.
