This bill aims to ensure individuals in federal custody receive prompt medical attention when experiencing distress. It makes it unlawful for federal law enforcement officers, Bureau of Prisons staff, and U.S. Marshals Service personnel to negligently withhold or delay immediate medical care if it results in unnecessary pain, injury, or death. Violators face penalties including fines and up to one year imprisonment. The legislation also empowers state attorneys general to pursue civil actions against officials who violate these provisions. Furthermore, it mandates that appropriate Inspectors General investigate all instances where such negligence leads to harm, with a requirement to refer cases for prosecution if negligence is found. To support compliance, the bill establishes a confidential complaint process for reporting incidents and requires agencies to provide training to covered officials on how to assist individuals in medical distress.
