Walls of Doubt

This article from today's Washington Post furthers the argument that building a border fence is more akin to political folly than a solution for undocumented immigration:

"This is the feel-good approach to immigration control," said Wayne Cornelius, an expert on immigration issues at the University of California at San Diego. "The only pain is experienced by the migrants themselves. It doesn't hurt U.S. consumers; it doesn't hurt U.S. businesses. It only hurts taxpayers if they pay attention to spending on border enforcement."
