Actually,
If the cars were illegally parked too close for
leonk19 to see around, then I believe he's in the right. However you'd have to take pictures of how close the car was and the need to peer around it. It sounds like he did make a complete stop, but had to compensate for another car.
Snapping on the police office was 100% without question the wrong thing to do. Plead your case, calmly and politely. But at the end of the day if the ticket is unfair, and you have your case prepared before hand you should be fine.
