Who enforces the Gun Laws?

In the United States, gun laws are enforced by a combination of federal, state, and local law enforcement agencies. At the federal level, the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) plays a key role in enforcing gun regulations. State and local police departments also enforce laws regarding firearms, including background checks, licensing, and restrictions on certain types of weapons. Additionally, prosecutors may be involved in enforcing laws related to illegal gun possession and trafficking.
