You have hit the nail on the head, I once sat in a court and listened to the evidence in a low flying case, the witnesses who were all claiming that the aircraft was within 500 ft could not agree if the aircraft was a high or low wing type.
The defence brief in this case was non other than The Flying Lawyer who walked all over the CAA case. I suspect that the CAA had little option to bring this particular case as the NIMBYS were ganging up and getting political, in the end it was the very people who started the ball rolling that provided such poor evidence that the made a not guilty verdict the only course of action for the magistrates.
