"The police car was in a convoy of two vehicles on a training run to test an electronic speed camera device." - taken from the new report.
Goes to show what injudicious reporting can do - the police officers were testing a VASCAR device which is not, by the common definition used here and elsewhere, a speed camera.
While not condoning the actions of the officers, it would be nice to have the same level of accuracy from our press as we do from our police officers.
