Nearly 700 miles of walls now separate the United States and Mexico. Would-be migrants still find ways over, under, through and around them. As a tool for controlling immigration to the United States, the border fortifications have been remarkably ill suited to the task. And yet these barriers are having a significant and lasting effect nonetheless: they are harming communities on both sides of the border.
We should tear them down before the damage becomes irreparable. After Sept. 11, 2001, President George W. Bush instructed the Department of Homeland Security to prioritize the construction of fortifications along the Mexican border. The result has been an astonishing array of barriers across America’s southern frontier. The number of Border Patrol agents doubled in seven years to more than 21,000. And interior enforcement was expanded to identify, detain, prosecute and deport undocumented migrants.
