For more than 40 years, the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) has been an agency that utilizes intelligence to direct our law enforcement and regulatory activities to combat gun violence and illegal firearms trafficking. ATF special agents, industry operations investigators, and other employees work with federal, state, and municipal law enforcement to protect communities from violent criminals and criminal organizations. The ATF has always been proud of the strong relationships we have with law enforcement agencies throughout the United States and around the world, and we are working to make those relationships even stronger. We work to complement, not supplant, the work of state and local law enforcement by offering insight into strategies and tactics geared toward the reduction of violent crime.
