The tabloids do a good job of reporting some stories. I like the video of the driver using string to operate his windscreen wipers, at the bottom of the Sun's speed camera article. The Daily Mail has provided plenty of detail too: https://www.dailymail.co.uk/news/ar...it-faulty-Southampton-Gatso-six-revealed.html
The article leads the reader to believe that the false speed readings were a known issue but nothing was done about it. That, IMO, is criminal complacency but I doubt anyone will carry the can for it. Andy
