Turns out we have been building one, for some time, and the 57 miles constructed just adjacent to San Diego (for the long-term retarded out there, just one of numerous similar builds underway, not the sole effort) is already helping there. Like you'd expect.
That's 57 miles where you can't just walk in.
Where 1 guy watching miles has time, if you try, to call in back up to pounce on you.
Where you can't cut through.
Where you can't bring in 80# backpacks full of dope.
Where a herd of 100 doesn't get through, including 10 guys who don't quite look like wetbacks, and are carrying Korans and prayer rugs.
For reference, the entire CA border with Mexico is only around 200 miles.
Imagine how much it's going to suck for Mexico, and their cartels, when there's 2200 miles of it, from the Gulf to the Pacific.
They might have to attempt the novel (for them, since ever) approach of unf**king their own hosed up country, instead of using the U.S as an economic tampon for their failed socialism, and then importing their misery here out of desperation.
And every time you shovel another load of illegals formerly here back over, they won't be able to just return the next day anymore.
What a concept:
Plug the leaks, then bail out the boat.
Almost like the people (including this blog) who tell you "Walls work" know what they're talking about or something.
One other happy thought:
