You definitely want to handle this properly. If you call or write the department about some crooked cop who isn't doing his or her job, you immediately put the department on the defensive. But if you call or write politely concerned that an error has happened and you don't want this on your driving record (even as a warning), you give the impression you are simply trying to take care of a mistake so that in the future, you are not held accountable for it. I would imagine with that approach, you're not coming to them with an axe to grind but are truly concerned about your driving record and your desire to keep it clear. I'm just guessing, but I get the impression you don't have a long list of tickets with law enforcement and therefore, with that kind of history, have the advantage of past driving responsibility and maturity on your side.
It would be an easy thing to let this go and forget about it, but if it were me, I would still pursue it for two reasons. I'd want my record clear and I would want to alert the department that something isn't quite right with one of their officers. Sitting at a desk writing tickets because it's easier than actual police work is not the way it's suppose to happen and again, gives a bad name to the honest police officers out there doing what they're suppose to do.
