Unfortunately it really dont matter if he is honest or not… all that matters is what the cop says, its his word against yours… who you think the judge is gonna believe 99.9% of the time?
As for the 3 points on the stop sign thing you are correct… I didnt realize that
“3323(b) failure to stop at a stop sign - 3 points”
That being said I would definitely go to court for it, they will probably drop the points and youll just have to pay the fine.
