Among all types of corruption, police corruption is probably the one that most directly hurts society, as those trusted with protecting the people either side with the criminals that victimize the citizens, or are themselves, criminals. However, both corruption and its effects are very difficult to measure quantitatively other than by perception surveys, but the perception that citizens have of this phenomenon may be different from reality. Using a simple agent-based model, we analyze the effect on crime rates as a result of both corruption and the perception of corruption within law-enforcement corporations. Our results show a phase transition in which crime can propagate across the population even when the majority of police officers are honest. We find that one of the parameters that strongly controls crime incidence is the probability that regular citizens become criminals. In contrast, other actions, such as arresting crime lords, or the amount of crime-associated money that is confiscated, have little impact on the long-term crime incidence. Our results suggest that in addition to combating corruption within law-enforcement institutions, to further reduce the incidence of crime, policymakers should strive to restore confidence in these institutions and the justice system.

Why do drug traffickers sometimes decide to use violence, but other times demonstrate restraint? Building on recent work on the politics of drug violence, this article explores how Central American drug trafficking organizations’ strategies impact their use of violence. I argue that three inter-related political factors—corruption, electoral competition, and the politicization of the security apparatus—collectively determine the type of relationship between traffickers and the state that will emerge. That relationship, in turn, determines the primary strategy used by traffickers in that country. Drawing on over two years of comparative ethnographic fieldwork in key transshipment points along the Caribbean coast of Central America, I show how co-optation strategies in Honduras have resulted in high levels of violence, evasion strategies in Costa Rica have produced moderate levels of violence, and collusion strategies in Nicaragua have generated the lowest levels of drug-related violence.
