If it's a case of mistaken identity, you'll be on your way as soon as it's cleared up. If it's a traffic stop, the officer will request your driver's license, registration and insurance card. If the officer saw you commit the violation, your statement isn't necessary. If your complaint is about the validity of the citation, then it must be handled through the courts. If the contact was unprofessional, complain to the police department.
Police departments have procedures for lodging complaints against officers.
Departments want to know if there's a problem with an officer.
