O’FALLON, Mo. (AP) — Killings rose dramatically across the U.S. last year, and a study suggests that the coronavirus pandemic and racial injustice unrest were factors. The study released Monday by the National Commission on COVID-19 and Criminal Justice, along with Arnold Ventures, looked at crime rates in 34 cities. It found a 30% spike in homicides in 2020 compared to 2019. Study leaders called for urgent action to improve relations with police and expand anti-violence initiatives. A study author says many officers were forced to quarantine last year, and maintaining social distancing kept them from the sort of community outreach needed to help stop violence before it happens.
