cyberfringe writes: A helicopter UAV equipped with infra-red cameras has been used for the first time in the UK to make an arrest. Thermal imaging transmitted to the officer operating the UAV enabled police to find a suspected car thief hiding in bushes in a thick fog. The UAV was originally designed for military reconnaissance but has been used in the UK for two years for search and rescue and to "crack down on anti-social behaviour". The drones are near silent and can hover or "perch" for hours. The UK already has more CCTV per capita than any other country, and now these mobile platforms are adding to its reputation as the "surveillance state".
