Significant Information Reports (SIRs) are a specific type of reporting mechanism used by the Department of Justice (DOJ) and the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) to document and disseminate information about events, incidents, or activities that have substantial implications for law enforcement operations, public safety, or national security.

These reports are intended to provide timely and relevant information to assist in decision-making, strategic planning, and operational responses.

Below, you will find an archived of these report listings, as released by the ATF to The Black Vault via the FOIA.
