(Newser) – A series of towers equipped with high-tech cameras now being tested along the Arizona-Mexico border could be the first step towards a "virtual border" for the US, the Los Angeles Times reports. The system, being tested in the busiest corridor for illegal immagrants entering the country,  could obviate the need for physical barriers.

It could also take the pressure of the Bush administration struggling to prove its seriousness about enforcement. The towers are equipped with heat-sensitive cameras that can pinpoint people as far as 5 miles away, even when they're hidden behind bushes.
