Sounds badass.A high-technology system to control the US-Mexico border with cameras and radar instead of a physical fence has gained government approval, US officials say. The $20m 'virtual fence' already covers 28 miles (48km) of the border between Arizona state and Mexico...
..."I have spoken directly to the border patrol agents... who have seen it produce actual results in terms of identifying and allowing the apprehension of people who are illegally smuggling across the border."...
...Its technology - including 100-ft (30-metre) unmanned surveillance towers equipped with sophisticated sensor devices - is capable of distinguishing people from cattle at a distance of about 10 miles (16km). The system's cameras and radars are powerful enough to determine whether people are carrying backpacks that may contain weapons or drugs.
