Media effects on public displays of brutality: the case of Mexico’s drug war

Abstract

ABSTRACTThis paper presents preliminary empirical evidence to show that media attention may influence public displays of brutality by Mexican drug cartels. We defined public displays of brutality as the presence of banners paired with corpses or dismembered bodies at unconcealed crime scenes. Using a data set of 857 such instances, we estimated reaction functions to determine whether public displays of brutality became more frequent when drug cartel violence was covered more by the press El Tiempo (1999). Our estimates show that public displays of brutality increase in a statistically significant way during the month following media coverage of similar crimes. We attribute this effect to changes in criminal strategy: increased brutality may be a way for criminals to more effectively deliver intimidating messages to their enemies. Whether increased displays of brutality also amount to increased crime rates, rather than merely increased visibility, is a question that remains to be studied.
