A fence is good. I never understood why we didn't man the border with the National Guard. It is task to protect the US from all enemies both domestic and foreign. And, these people are the enemy since they are trying to colonize the US and are draining our public assistance funds and bringing in 3rd world disease.
The border should be heavily manned until the pont that a fence can relieve some of the human support. With all the electronic innvocations of today, we should be able to shut it down to a trickle.
I was horrified when we moved to AZ in 1990 and I realized how many people were coming in illegally. I had called Border Control to ask about it since my son was denied the services he needed in school because of the drain on the education funding of English as a Second Language. I learned so much, all the ins and outs, as I had a long conversation at that time, probably an hour or more of conversation.
What a nightmare and it worse everyday.
