This bill mandates the Attorney General, in consultation with the Secretary of Health and Human Services, to annually acquire data concerning interactions between law enforcement officers and individuals with mental illness. The Attorney General is also responsible for establishing comprehensive guidelines for the collection of this crucial data. The acquired data is strictly limited to research or statistical purposes and must not contain any information that could reveal the identity of an individual. An annual summary of the collected data will be submitted to Congress and made publicly available, ensuring transparency and informing policy. The bill also authorizes appropriations for fiscal years 2026 through 2036 to support these data collection efforts.
