I would do one of two things if I were you. First, if neither one of you want to go forward with this since you were both issued citations for the same incident see if the officer would be willing to withdraw the citations. If that does not work I would maintain that you held off on any kind of physical action until you felt that you no longer could do that. Tell the court that you have had training in matters similar to this and you only employed the methods you have learned in order to control her. Use your training and knowledge as a defense to this citation.
I hope this was helpful and informative.
