Really none. You are being cited for violating the law and being served by a process server instead of a police officer, which is the other option, for speeding offenses. Only law enforcement can file charges of trespassing in the criminal courts through the DAs Office. As such, you are wanting to have law enforcement charge themselves for serving you with the criminal charges. Yes, you could try to sue them civilly, but you have no economic damages. This is simply not a fight that is worthwhile. Like it or not, the cops can and will make life a living hell for you basically without any ramifications. We see clients impacted by cops who target them all of the time and their lives are terrible.
