Unmarked following you home on the same exact time you leave court after winning your case coincidence? , sour grapes?
....The same two officers who originally stopped you? Surely just leaving court the same time as you and going back to base.
How did you know it was Police if unmarked? Little blue lights hiding away? Or was it paranoia?
It's all very well to say it was a waste of time and public money after the event has been proved to be innocent but we must accept other people's points of view and not judge the Police as acting in a way to cover up their mistake. It doesn't mean that they weren't covering up but remember that
everyone is innocent until proved guilty.
I think that the OP was absolutely right to have insisted on his innocence and on going to court. I think that it was absolutely right for the Police to prosecute as there was clearly an element of doubt. The court, as it is designed to do, dispensed fair justice. So I don't think this case was a waste of time or 'public*' money - (*It's no longer
your money once it's handed over in tax etc).
As said before, I'm very glad to see that Police are coming down hard on mobile phone drivers. They were over zealous in hindsight but were doing their job.
