Nice "cut and paste" and your personal opinion is?
The whole legality of cameras has been questioned for years, accept the fact that speeders have been knicked from the days of coppers hiding behind trees with stop watches, though radar dishes on the side of the road to radar "guns" and now cameras all over the place.
Remember when the white stripes appeared on the road in front of cameras, after the "where is the corroborative evidence" shout went up. In short this is a big juggernaut with a few minor leaks that WILL ALL get plugged as she ploughs on. If you speed accept the the fact gracefully when you get caught.
Would you want a mass murderer to get off on a technicality like the copper didn't caution the arrested correctly? Minor points off law.
By the way, I hate speed cameras and the safety argument in a lot of cases is totally invalid but they are a fact of life and we have to live with it.
