Explanation:It has been more than a year since the first calls to release people from jails, prisons, and detention centers during the COV.ID.-19 pandemic. At the end of March 2021, there were nearly 1.8 million people still incarcerated in the United States, down only 2 percent since June 2020—there was a 9 percent decrease in the prison population, but that was offset by a 13 percent increase in the jail population. In the face of continued demands for change, most politicians and policymakers failed or refused to do more. Instead they have tolerated widespread COVI.D-19 outbreaks in jails and prisons across the United States.
