Reducing the use of jails is important to fighting the spread of COVID-19. A joint statement from Association of Prosecuting Attorneys, Center for American Progress, National Center for Victims for Crime, National Legal Aid & Defender Association, and R Street Institute calls for cities and counties to continue taking action to address this public health threat. They highlight the many jurisdictions in the Safety and Justice Challenge that are using proven justice reforms to reduce their jail populations and argue that safely doing so is critical as the world faces a public health crisis.
