Gun Violence Prevention Through Financial Intelligence Act

HR 4158 requires the Financial Crimes Enforcement Network (FinCEN) to collect financial data from banks and other financial institutions within one year to better understand how domestic terrorists and violent extremists obtain firearms. FinCEN must develop an advisory on suspicious gun purchases by 540 days after enactment, or report to Congress if insufficient data is gathered. The bill also mandates FinCEN to define key terms like "lone wolf" and "firearm accessory" within 90 days, working with the FBI and ATF. This process directly affects financial institutions, which must provide tailored data, and agencies involved in gun violence prevention. The bill focuses on data collection and analysis, not changing gun laws or imposing new restrictions.
