Which agency enforces federal laws related to firearms, explosives, and alcohol/tobacco, and investigates illegal trafficking?

• A. FBI (Federal Bureau of Investigation)
• B. DEA (Drug Enforcement Administration)
• C. ATF (Bureau of Alcohol, Tobacco, Firearms and Explosives)
• D. ICE (Immigration and Customs Enforcement)

Answer: (C)

Focus on who regulates and enforces the rules for firearms, explosives, and alcohol/tobacco, and who investigates trafficking in these items. That responsibility lies with the Bureau of Alcohol, Tobacco, Firearms and Explosives. This agency oversees licensing and background checks for firearms, regulates explosives and their safety, and administers laws related to alcohol and tobacco (including tax and distribution rules). It also investigates illegal trafficking in these products, such as gun and explosive material trafficking. Other agencies have different focus areas (for example, the FBI handles a broad range of federal crimes, the DEA concentrates on drugs, and ICE handles immigration-related enforcement), so ATF is the one whose scope matches all three categories in the question.
