In Latin America, high levels of crime have prompted many politicians to embrace zero tolerance policing in order to quell public fears. While the overall impacts on urban crime are debatable, zero tolerance in the region has morphed into a powerful policy narrative that symbolizes strong leaders who crack down crime and disorder. Its impacts have been far-reaching; to date, it has been implemented in various guises in Mexico, Brazil, Ecuador, Venezuela, Chile, Argentina, Honduras, El Salvador, Guatemala and the Dominican Republic. Yet, the policy transfer of zero tolerance to Latin America has mutated into a much more punitive approach. In this paper, I develop a critical analysis of the punitive inequalities of zero tolerance policing in Latin American cities, and the consequences for marginalized and racialized youth. I also explore the emergence of a new, unexpected consequence of zero tolerance: the South-North migration of undocumented people.
