The MAIL Theft Act of 2024 directs federal agencies to develop a coordinated strategy for investigating organized postal theft within 180 days of the bill's passage. The law requires the Attorney General, Secretary of Homeland Security, Postmaster General, and other relevant agencies to improve information sharing about postal crime networks, assist state and local law enforcement with prosecutions, and increase cooperation between federal and local authorities. Within the same 180-day timeframe, these agencies must submit a joint report to Congress detailing their strategy. Additionally, the Government Accountability Office must publish a separate report within one year examining how private sector and law enforcement coordination can better deter and investigate organized postal crime. The bill affects federal agencies, state and local law enforcement, and ultimately aims to reduce mail theft and related criminal activities.
