Most know the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) by name—but few in the fire service fully understand the agency’s mission, resources, and how it supports local fire departments. This workshop pulls back the curtain on the real role of the ATF, with a focus on its Fire and Arson Investigation Division. Learn how ATF collaborates with state and local agencies, provides investigative expertise, and deploys National Response Teams to complex fire scenes. Attendees will gain insight into ATF capabilities, case support, and how to build strong, effective partnerships. Whether you're a fire investigator, command officer, or fire marshal, this session answers the question: Who is the ATF... really?
