To American public it's a 2,000-mile-long project to keep illegal immigrants, narcotics, and terrorists on other side of U.S.-Mexico border. In deserts of Arizona, it's a virtual of high-tech electronic sensors, cameras, and radar. In some border stretches it's a huge concrete-and-steel wall; in others it's a series of solitary posts designed to stop drug runners; in still others it's rusted barbed-wire cattle fences. For two-thirds of international boundary it's nonexistent. Just what is this entity known as the fence? And more important, is it working? Through first-person interviews with defense contractors, border residents, American military, Minutemen, county officials, Customs and Border Protection agents, environmental activists, and others whose voices have never been heard, Robert Lee Maril examines project's human and financial costs. Along with Maril's site visits, his rigorous analysis of government documents from 1999 to present uncovers fiscal mismanagement by Congress, wasteful defense contracts, and unkept political promises. As drug violence mounts in border cities and increasing numbers of illegal migrants die from heat exhaustion in Arizona desert, Maril argues how fence may even be making an incendiary situation worse. Avoiding preconceived conclusions, he proposes new public policies that take into consideration human issues, political negotiation, and need for compromise. Maril's lucid study shows fence to be a symbol in concrete, steel, microchips, and fiber optics for crucible of contemporary immigration policy, national security, and public safety.
