Didn't work for me :(
I was forced to overtake a police car when he deliberately braked. I was accused of overtaking him over double white lines around a bend, this was BS!
I took an enlarged a map of the bend to court and got the officer to answer six questions. The stupid bastard did not realise that he could only answer any five of them with a yes. One of the questions was agreeing on my speed (50mph). I then showed that I would have had to be driving at 100mph to overtake him in the agreed distance. I was found guilty but got off at an appeal when I had discovered that the arsehole had emigrated* and so there was no evidence offered. Ha ha!
