2. You only need to prove that the cop , from his point of view, was UNABLE to see you if you stopped there.
By proving this:
1) Park your car at the stop sign and take a photo of it from the cop's position.
2) Draw a map of the intersection. You can print a map from google map satellete.
3) Write down what you prepare to say in the court and review it several times.
Good Luck!
