In the Hyde area of Manchester England a motorist was caught by a Speed Camera (Photo Radar) system, but not just for speeding. The motorist realized a radar system got him when the camera flash alerted him to the yellow speed camera (all UK speed cameras are painted yellow). The motorist was so enraged he reportedly back tracked and blew up the speed camera. The camera was damaged and rendered useless, however images of him speeding and returning to the scene were preserved (in the base located below the camera). The motorist got 4 months jail time (and probably a speeding ticket -- the least of his current problems).
Many UK speed cameras are fixed mounted, usually to a utility pole. Typically in the UK when a motorist goes after a speed camera they usually use an ax or paint. In 1983 the state of Texas (USA) tried a portable French-manufactured Ka band radar for a time but discontinued it's use because the units were being stolen. Photo speed cameras (photo radars) are extremely unpopular with the public worldwide.
