Social scientists from different fields have identified security as a future-oriented mode of governance designed to preserve the social order from diverse types of global risk through international cooperation, militarization and privatization of the state security apparatus, surveillance technologies, community policing, and stigmatization of identities and behaviors deemed dangerous. This literature has largely been limited to English-speaking countries in the Global North, however, that are relatively “secure.”. To understand how security operates in a different context, this article focuses on the (...) current War on Crime in México using newspaper and magazine articles, government documents, and extant academic research. In México, it is argued, the basic elements of security governance (international cooperation, militarized police, surveillance technologies, law, etc.) are present, but in modified form. Rather than focusing on external risks that could develop into future threats, security in México is turned inward against traditional forms of national economic, political, and cultural life thought to produce harm in the present. This, in turn, underscores security’s unique purpose in the country, which is not to preserve the prevailing social order, but to transform an emergent social order that through globalization has come to threaten the state’s legitimacy. These observations suggest an international divide in the operation of security that leaves those most vulnerable in the Global South to bear the greatest costs. (shrink)
