Areas in red coincide with the COVID-19 pandemic. During the pandemic, the criminal legal system has operated completely differently than it normally does. The changes that can be observed on our dashboard include: 1) isolation, closed schools, and the loss of community programming has led to an increase in serious violent crime, 2) police have made fewer arrests overall (in particular for minor offenses), 3) court policies and other restrictions meant to keep people safe have also disrupted or delayed court hearings and led to a significant increase in open cases forced dismissals and withdrawals.
