La inseguridad cotidiana que afecta a varias zonas de América Latina, combinada con altos niveles de exclusión que afectan a gran parte de la población general, se ha transformado en caldo de cultivo para que actores criminales no estatales intenten corromper a funcionarios públicos del sector seguridad, incluyendo funcionarios penitenciarios. Para que la cárcel pueda cumplir su función social de contribuir a la seguridad pública y a la reinserción, deben existir adecuadas condiciones de vida para internos y funcionarios, además de un ambiente penitenciario “humano”.The daily insecurity that affects several areas of Latin America, combined with high levels of exclusion suffered by a large part of the general population, has become a breeding ground for corruption, where non-state criminal actors try to corrupt public officials related to the public security, including prison officers. A key aspect for the prison to fulfill its social function of contributing to public security and social reintegration is the environment and living conditions for inmates and officials. This article, based on Alison Liebling's concept of “moral performance” and using a qualitative methodology, presents two case studies that analyze the relational nature of prisons and the way in which the officials of both precincts perceive their role and how they relate to inmates.
