Seems there would be better options to keep these trespassers out.

You want to secure the border:

1. Crackdown on the companies hiring the illegals. Jail the key company officers who order and/or do it. Seize the company assets and sell them at public auction with monies being applied to the national debt.

2. Create a five mile wide DMZ type area along the border complete with minefields, no less than three full divisions of troops, artillery, air support and everything else needed to secure it as best as is humanly possible. Any thing or any one caught inside the DMZ area will be eliminated on sight.

3. Inform Mexico that if they do not stem the flow of people across the border on their side it will be considered an act of war and dealt with accordingly.

4. Declare all the drug cartels terrorist organizations and let the military loose on them.

What do you want to see?
