Homeland Security Secretary Janet Napolitano to freeze funding.
Homeland Security Secretary Janet Napolitano plans to freeze funding for a virtual fence along the U.S./Mexico border. The electronic security system, known as SBI Net, is a network of sensors and cameras. It was supposed to cover the border by 2011, but it's been plagued by technical gliches and delays. The government has spent more that $20 million dollars with little to show for it.
