It appears the fence idea needs to be raised a notch or two. Maybe the fence needs to electrify.

The point is the American people want the Illegal Border Crossing to STOP. The solution to the problem is in that demand. The method is immaterial. The Illegal Crossings must STOP. North Korea STOPS Illegal Border Crossings. What the US needs to do is look at the North Korean success and copy it. Mexico sure will not STOP the crossings.
