The cost of freedom

U.S. Sen. Jeff Sessions, R-Ala., understands that illegal immigrants would never try to climb over a 2,000-mile fence along the Mexican border. And that the fence wouldn't destroy America's relations with our second-largest trading partner. And that people around the world wouldn't get the wrong idea if they saw us erecting a giant Berlin Wall-type barrier to separate ourselves from one of our closest allies.

Maybe it should have electrified barbed wire, too.
