The book examines the United States Border Patrol's (USBP) deployment of fencing and vehicle barriers along the U.S. southern border to impede the illegal entry of pedestrians and vehicles. Begun in 1990 and buttressed with a secondary layer of fencing in 1996 to deter illegal entries and drug smuggling in the San Diego sector, the USBP's 14 mile-long San Diego "primary fence" formed part of its "Prevention Through Deterrence" strategy to reduce smuggling and illegal migration by placing agents and resources directly on the border.
