Pickens writes "The Arizona Republic reports that the federal government has officially cancelled its multibillion-dollar plan to build a virtual fence along the border with Mexico as Homeland Security Secretary Janet Napolitano disclosed in a congressional briefing that the program known as SBInet was costing too much and achieving too little. 'SBInet cannot meet its original objective of providing a single, integrated border-security technology solution,' says Napolitano. Boeing was hired in 2006 to develop the system under a three-year federal contract with cost projections for full build-out as high as $8 billion but efforts were plagued by delays, glitches, budget increases and congressional criticism. Napolitano has ordered Customs and Border Protection to launch a more modest and geographically tailored effort using SBInet funds and existing technology such as mobile-surveillance systems, unmanned aircraft, thermal-imaging devices and remote-video surveillance with proven elements of SBInet including stationary radar and infrared-sensor towers. SBInet cost nearly $1 billion for development along 53 miles of Arizona border."
