If it goes to court, Magistrates always, in my experience, side with the Police. If that is the case you'll need to take it to a Crown court.
If what you say is even half accurate, you're not going to get 12 jurors to convict you. But you do need to spend money on a lawyer/Barrister/Solicitor. A Good lawyer commands so much respect from the court, you're much more likely to get a reasonable result (That especially applies in the Magistrates court).
