My point is that if there is a demand there will be a supply. Just like there is a demand for illegal cocaine that is apparently imported en masse. I did not mean to infer that people in the US are currently importing illegal guns en masse however the is a current market for illegally imported guns. Without a tightly controlled border how can the US keep out illegal guns, cocaine or any other banned item?
Don't need to import them. We've got hundreds of millions in the country already. Even if you shut the border down you'd just raise the price on the street - just like drugs.
