Thanks for showing the picture of the border as it really is. We can't shut this border down without a major effort by the military including concertina wire, minefields, watchtowers and dogs.
I, for one, don't want to see that happen. I think you shut off the spigot at the source: employers.
Send a few businessmen and society wives to jail for employing illegals. No exceptions, no excuses.
Then set up a tightly regulated bracero program.
