If the illegal immigration problem was a few Mexican nationals slipping across the border to work we probably wouldn't have this discussion, but it is not. It fuels a whole criminal enterprise that not only includes drugs, but kidnapping and slavery. Central Americans are being kidnapped and put in slavery in southern Mexico, baited by an offer of a trip to the US. People our being kidnapped and held for ransom in southern AZ. There are shootouts in highway rest stops over cartel territories. The list doesn't end there, they also catch Chinese, Arabs, and other nationals attempting to sneak into this country.
So Flytier57, you prefer an anarchist approach to immigration rather than orderly controlled one?
