Even if the fence is not very efficient, it sends a message that this country is SERIOUS about stopping illegal movement across its borders.
Sure, Guard patrols and employer sanctions are good ideas too. But they are not permanent.
One governor can send out the Guard, another can quietly recall the Guard. And poof! it's all forgotten.
Same goes with employer sanctions. One administration can enforce them, the next one can ignore them.
But a fence is always there. It's a constant reminder.
It sure is. Just look at those illegal aliens in the video jumping over Border Fence like jack-rabbits.
It is a symbol of, "Look at what those dumb Gringos spent $3 Billion on? A Climbing Wall for our exercise! Hahahaha!!!!"
If you want to get rid of illegals, start hitting illegal EMPLOYERS hard.
When the heat is on and the jobs dry up, illegals deport themselves.
