What will be your actions in response to the matter?

As the head of the professional standards unit in your sheriff’s office, you are assigned to address the following letter, received by your sheriff. What will be your actions in response to the matter?
Last night my 17-year-old daughter, Jamie was stopped by one of your deputies for speeding. I do not know the deputy’s name, but his badge number is 336. I don’t know what kind of people you have in your agency, but this one got very sarcastic with my daughter and said some things that weren’t very nice. He even told her that if she would go out with him on a date, he wouldn’t give her a ticket. When she told him that she would not go out with him, he gave her a ticket. I know a dispatcher there, and if I don’t hear that this deputy is disciplined for his behavior, I will send a letter to the County Commission as well.
