Im sorry, but this has no place, at the end of the day you got points for speeding end of story, it was a 30 whether you are overtaking or not, you cannot exceed 30. The officer was right to prosecute.
A couple of thoughts for you.
Would you want to be called to a disturbance in a pub, full of drunken people, with a fight starting to break out, with backup on the way but not immediately there, and you have to start to bring the situation into calm?
Would you like to attend accident scenes where some child has been hit my a car, and because of there size has gone under the car rather than over the car, with all the ensuing blood and and other debris strewed around the scene.
I personally think the Police have a hard enough task, without someone who is bitter with getting points and a fine, having an attempt at smearing them. I am not a police officer, I did apply to be but was turned down due to my stutter.
Just one final thought, on average the number of deaths on the roads is at least ten times the number of people murdered in this country, now that in my book makes a serious crime, and that is something we are acheiving without trying to kill people, so if we went out with the intent of killing, just think what a massive figure we could muster.
