In the United States, the number of so-called progressive prosecutors focused on criminal justice reform has risen, but few studies have addressed the relation between these prosecutors' policies and crime rates. In a new study, researchers examined whether progressive prosecutors in the 100 most populated counties affected crime rates from 2000 to 2020. They found that the inauguration of these prosecutors led to higher relative rates of property crime and total crime, but not to higher relative rates of violent crime.
