This article addresses the terrorist acts perpetrated by illegal armed actors during 1990-2000, as well as the policies related to national security. The role of a society in the relationship with terrorism is stressed as a coercive method used to gain control over government and groups of people. Terrorism and power relations based on violence and fear are used as a means of coercion to create states of anxiety. This study approaches three thematic axes. First, the general aspects of the concept of terrorism and the incidents in the Colombian system are studied. Then, public policies are analyzed, focusing on security in Colombia, opening the way to the third axis in which an analysis is carried out to determine their effectiveness and whether they are an asset to justice. This study seeks to determine the efficiency of public policies in matters of security related to transitional justice regarding the conflict with the FARC in the Colombian state. To conclude, brief conclusions are provided.
