There was a programme on BBC1 last night that tested hand-held speed cameras as used by the police here.They showed a car recorded as doing 8m.p.h. despite the minor detail that it was standing still at the time.Better yet they clocked a brick wall at 4 m.p.h. Apparently this can be caused by a slight movement of the operator,unless he`s stood stock-still it wont read a true speed.
