These people are a lot more tolerant than I would be.
The border crossing at Naco should be closed, and entry to the USA should be possible only through Douglas to the east or Nogales to the West. If the number of illegals then continues at the present pace Douglas should be closed and the next border crossing should be at Juarez/El Paso. Given the great number of illegals that enter through the Toono Oodham reservation the crossing at Sonoyta should be closed -- which would have a tremendous and negative impact on Puerto Penasco/Rocky Point tourist area. In all cases the Mexican government would scream bloody murder, but the only way to get its attention is with a 2x4 across the temple.
