Police defend speed gun after RM's rap.
Police have defended their use of a speed-detection system to catch motorists after questions were raised by a leading Residential Magistrate.
RM Mark Hamill has questioned the Visual Average Speed Computer and Recorder (VASCAR) speed detection sytem used by cops across the province.
Mr. Hamill has said for a second time in court that there is room for human error in the way the speed is calculated by officers operating the system.
Vascar is a timing computer that assesses the average speed of cars over a distance. It is one of the favoured methods used by police to catch speeders.
According to the Vascar website, officers use a fixed point such as a bridge or a marker on the road as the start point for them to start the system. When the vehicle passes the second position, they then press the button again, giving an instant average speed.
But Mr. Hamill said, after hearing details of another case of a motorist speeding at 101mph, that if human error in this system can be proven scientifically, then speeding charges would be open for contest.
However, police have rejected any criticism of the use of the system. A Police Service spokesman said:" Officers operating Vascar equipment have to attend a week-long course on its opeartion and pass a practical examination before being deemed qualified to use it. Also the equipment itself is subject to rigorous calibration prior to it being deployed and these checks can be verified by examination of the system.
"Vascar is used by many, if not all, UK police forces and, indeed in other parts of the world. It has been used by police in Northern Ireland for over three decades and because of the training required for its operation and the calibration checks, is seen as a reliable piece of equipment."
