I don't know the dynamics of everything that happened, except for your few words!
I don't see where the infraction was committed, of which, this policewoman has challenged you the reason to be out there by chance!
In any case, if you had taken witnesses with you, who would have proved you right, you could have challenged the policewoman through the judge.
Why can these people on duty have the best, to be public officials?
If you don't have any witnesses, their statement, even if it is false, prevails over yours! Don't think that whoever is in the service of the police can be saved, they will be accountable to God, for what they have done in their earthly life.
Hell cannot be bought with dollars so as not to go out there!
