DHS should swarm that county with Boarder Patrol agents. Just the present of BP should scare the hell out them.
Why not Ice agents.
Instead of trying to force these local taxpayers to pay for enforcing federal laws, you and all the enforcement only goof-heads should be willing to spend the money(your money) to enforce the law.
There-in lies the problem: You and many others say all these problems can be solved by spending more and more money on enforcement. Over the last 17 years, lots of enforcement money has been spent, but you have nothing to show for it. Now you want Mexico to pay for it. Now you want locals to pay for it.
Come up with more money Mr Cheapskate.
