Thirteen years ago, the Border Patrol began to build a wall extending 14 miles along the Mexican border south of San Diego. Part of it was made of old landing mats from Vietnam; other parts were erected from steel mesh. Before the wall, it was estimated that over 500,000 illegal immigrants streamed across that stretch of California each year. By 2005, the New York Times reported, that number was down to 138,000. The area’s crime rate also dropped significantly.
