In a lengthy and complex speech in which Johnstone used the laws of physics and Newton's third law to explain his point, he questioned the accuracy of the speed camera arguing that when it had been installed that day the static box in which it was housed had not been checked.
He said the camera instructions stated that to work correctly it needed to be positioned at an angle of 20 degrees but that measurements he had taken showed that the housing had moved and this was not the case.
Too bad the reporter can't be any more explicit on the nature of the argument. It could have been rather utterly fascinating for someone like me, or completely hysterical that I could not stop giggling. Either way, I wouldn't have been bored, I don't think.
