This bill addresses the growing problem of organized mail theft and related fraud crimes by establishing new coordination mechanisms and toughening penalties. It requires the Attorney General to designate a Mail Theft Coordinator in each federal judicial district to oversee investigations and prosecutions of mail theft, postal key theft, identity theft, check fraud, and related crimes stemming from stolen mail. These coordinators will work with the Postal Inspection Service, FBI, Homeland Security, Treasury Department, and state and local law enforcement agencies to combat organized mail theft schemes. The bill also directs the Attorney General to submit annual reports to Congress for six years detailing trends in mail theft prosecutions, coordination efforts, and recommendations for improvement. Additionally, the United States Sentencing Commission is required to review and update federal sentencing guidelines by May of the first full calendar year after enactment to ensure appropriate enhanced penalties for mail theft offenses, particularly those involving postal key theft, large-scale schemes, identity theft, violence against postal workers, and crimes affecting multiple victims or causing substantial financial losses.
