Night watchers and terrorists

摘要

A massive movement of Night Watchers or vigilantes' patrols emerged among the most impoverished indigenous communities in the Andes at the end of the twentieth century to combat terrorism. Northern peasant patrols based their organization on democratic mechanisms while the southern patrols built a hierarchical structure. How does the variation of external threats shape the variation of governance structures and collective responses within extralegal groups? To organize the provision of security and defense against terrorism, these Night Watchers required mechanisms to control opportunistic behavior and prevent internal predation. This article develops an organizational theory of defense. The time horizon explains why the Night Watchers produced arrangements in vertical or horizontal forms. Peasant vigilantes depended on hierarchical mechanisms to enforce their agreements if and only if they confront a short time horizon and existential threat. Comparative analysis of the northern and southern Peruvian communities provides empirical support for the theory. (C) 2020 Elsevier B.V. All rights reserved.
