For everything that is attempted to control border security, it will be always ham strung by one thing: Commerce.

Sadly, illegals and illegal goods tend to piggy back legitimate commerce routs.

And the reality is, even though most people don't understand what commerce is happening there, the U.S. would be hurt worse by limiting commerce then the gains from securing the border could offset.

I wish there was an easy solution, but a simple lock down really isn't as feasible and effective as its often made out to be.

Now, if we stirred the Mexican people to take their power back from the cartels and corrupt government that abuses them in a middle east style upheaval...

(I do, however, agree that individual land owners have rights. If your property edges the border, that does not invalidate your right to protect your property. "Sorry, asshole, you're not just in America, you're on my lawn")
