Crime under lockdown: The impact of COVID-19 on citizen security in the city of Buenos Aires.

We find no evidence that the reduction in the number of detainees from outside the City of Buenos Aires led to a displacement of crimeto suburban areas. This result aligns with the hypothesis that focalized place-based interventions have the potential to reduce overall crime rates. Moreover, the increase in arrests for "resistance to authorities" at the checkpoints set up during the lockdown shows that the enforcement of mobility restrictions can cause frictions between citizens and police, negatively affecting police's legitimacy. We also find that the increased government presence for the provision of health and social services in informal settlements during the pandemic led, as a positive externality, to an additional decrease in crime.
