I suspect something is being setup from within the DHS. Recently, a week or 2 ago, about 160 undocumented immigrants were turned back at the Tijuana border after coming into the DHS facilities there.
Only about 40 of them were Mexican origin. Mexico took them back, but refused the others. Locals believe the US wasn’t being fair in sending these back to Mexico, but should have turned them back to the countries of origin.
These situations appear reasonable, but also appear to have been contrived setups, attempting to stir up badwill amongst our neighbors.
Solution is to make the situation for the illegals in the US worse than their alternative to find a way back to their nation of origin, when they aren’t seeking legitimate immigration and US citizenship.
Why do you refer to illegal aliens as “undocumented immigrants?”
