You don't need 25 guards per mile. You need a wall with guards that make it a less-than 50-50 proposition that an illegal entrant will make it over the border.

Then you have inland patrols that will catch another 10 percent or so.

And then you place harsh penalties on companies that repeatedly hire illegal aliens. And cut off illegals from educational and all but emergency medicine - and they get deported afterwards if they do get emergency help.

In other words, you make it a losing proposition to come here illegally.

Good luck building a wall in my corner of San Diego County. You planning on hiring a s**tload of coolie labor to haul the materials in? (A large chunk of the border trace is NOT traversable by vehicle, nor accessible to construction equipment, but is rather easily traveled on foot.)
