While the completion of the final 670-mile stretch of security fence along the U.S.-Mexico border continues to be slowed by political and engineering issues, across the more than 600 miles of fence already completed (“a hodge-podge of metal panels, wire mesh and steel posts”) “drug smugglers . . . continue to breach the fencing that is up, forcing Border Patrol agents and contractors to return again and again for repairs. The smugglers build ramps to drive over fencing, dig tunnels under it, or use blow torches to slice through. They cut down metal posts used as vehicle barriers and replace them with dummy posts, made from cardboard.”
Teddy Cruz, reporting for “The Nation,” writes that “no matter how high and long the post-9/11 border wall becomes, it will never stop the migrating populations and the relentless flows of goods and services back and forth across the formidable barrier that seeks to exclude them.” Yet from the southward flow of materials something remarkable is being created – “while human flow mobilizes northbound in search of dollars, the urban waste of San Diego moves in the opposite direction . . . The leftover parts of San Diego’s older subdivisions — standard framing, joists, connectors, plywood, aluminum windows, garage doors — are being disassembled and recombined just across the border. A few miles south, in Tijuana, new informal suburbs — some call them slums — spring up from one day to another. This river of urban waste flows across the Tijuana-San Diego [sic] to make something dramatically new.”
