Long story short, imo, they didnt want to have the judgement of one of their officers put under scrutiny, and with my badgering for the statements of the other officers, and the mysteriously missing camera footage, it never made it to the court date.
Ultimately, given by the time if it made it into court, the judgement handed out and the warning quashed from police records, it would have been nearly 12 months on and the warning expired, one could argue they "won" regardless.
Also made several procedural mistakes due to having to learn as I went along, which meant I only got to recover my court costs and not any billable time. So no fat payday either.
However, to be proved right is the most important thing, and with the knowledge I now have on top of the hidden(ish) dashcams, will happy go another round with any irate idiot officer who pulls me in the future.
