The purpose of this paper is to describe how a set of audiovisual productions have been commissioned to reconstruct sections of the demobilization process of the paramilitary groups in Colombia, AUC. These productions have been concerned with capturing the reality of the victims and unraveling the rational context of the demobilization. For this, we use the Biopolitical and Governmental approach developed by Michel Foucault in the period known as the Paris Courses. In the methodological aspect the article focuses on the analysis of the documentary Impunity (2010) that privileges the analysis of power relations, on aesthetic aspects and the way in which thisdocumentary gathers the manifest tensions between different rationalities that are in conflict in the Colombian context.
