Illegal guns continue to pour into New York via the Iron Pipeline The Iron Pipeline The Iron Pipeline is the term given to how guns are trafficked from the South, where gun laws are lax, along Interstate 95 to New York and other states where the laws are much more strict. NEW YORK - The guns are here in New York City and they keep coming. "90% of these guns don't come from New York. They come along I-95 — they come from states with lax gun laws," New York Attorney General Letitia James said at a recent gun buyback event in Queens.
