Gun Violence Prevention Through Financial Intelligence Act

HR 4220 requires the Financial Crimes Enforcement Network (FinCEN) to request data from financial institutions about how firearms and accessories are purchased, specifically focusing on patterns linked to homegrown violent extremists and domestic terrorism. It sets a one-year deadline for collecting this information, with FinCEN needing to develop an advisory within 540 days or report to Congress if data is insufficient. The bill also mandates defining key terms like "lone actor" and "homegrown violent extremist" to guide the data collection process. This is a data-gathering step for law enforcement agencies (like the FBI and ATF), not a new law restricting gun sales or ownership.
