Gun trafficking occurs when individuals purchase or obtain firearms in the United States and illegally trade or transfer those firearms, often across borders or jurisdictions. Gun trafficking is often associated with organized crime, violence, and the circumvention of legal controls designed to prevent the illicit proliferation of firearms.
