Police have unveiled their new weapon - Britain's biggest speed camera that can film a car a THOUSAND meters away and dubbed 'The Long Ranger'. The massive gun has been showcased at the launch of the pilot project called Operation Indemnis. Police in Gloucester are using the whopping camera to tackle motoring offences such as speeding and tailgating. Speed guns have been able to detect how fast cars travel but the new camera produces clear video footage and still photographs of the people inside them.
