The National Statistics on Deadly Force Transparency Act of 2025 requires the Attorney General to issue regulations within six months for the comprehensive collection and compilation of data concerning the use of deadly force by law enforcement officers across all levels of government. These regulations will be developed in consultation with various stakeholders, including Federal, State, and local law enforcement agencies, as well as community, professional, research, and civil rights organizations. The data collection mandates specific details for each incident, such as the date, time, location, and nature of the deadly force used, including whether a firearm was involved. It also requires information on the alleged criminal activity of the target, any non-lethal efforts employed, and the agency's explanation and guidelines regarding the use of force. Crucially, the regulations will require demographic characteristics of both the officer and the target, including race or ethnicity , gender , and approximate age , but explicitly prohibit the collection or public release of personally identifiable information. Law enforcement agencies will be required to use a standardized form to submit this data to the Department of Justice Bureau of Justice Statistics, and to maintain records for at least four years. The Bureau of Justice Statistics is then tasked with providing this aggregated, non-personally identifiable data to Congress and making it publicly available. To ensure compliance, any State or local government that substantially fails to meet these reporting requirements will face a 10 percent reduction in their Byrne Justice Assistance Grant funding for the subsequent fiscal year.
