The stay-at-home restrictions to control the spread of COVID-19 led to unparalleled sudden change in daily life, but it is unclear how they affected urban crime globally. We collected data on daily counts of crime in 27 cities across 23 countries in the Americas, Europe, the Middle East and Asia. We conducted interrupted time series analyses to assess the impact of stay-at-home restrictions on different types of crime in each city. Our findings show that the stay-at-home policies were associated with a considerable drop in urban crime, but with substantial variation across cities and types of crime. Meta-regression results showed that more stringent restrictions over movement in public space were predictive of larger declines in crime.

The extent to which police officers obey instructions and policies is of permanent concern to police leaders and the community. This is especially the case when it comes to preventing police misconduct, such as the use of excessive force. In the current study we examined officer compliance from a procedural justice and social exchange perspective. Using data collected among 536 police officers of the Metropolitana Police in Buenos Aires, we explored to what extent internal procedural justice and trust are related to: (1) officer compliance with supervisors and policies; and (2) officer endorsement of regulations on the use of force. The results indicate that perceptions of fair treatment by supervisors and trust in supervisors are positively associated with (stated) compliance. Our findings suggest that a procedural justice approach may facilitate the implementation of police policies and contribute to preventing police violence.
