Seatbelt ticket
Go to court. Clean up and dress nice. Explain the situation clearly and succinctly (write down what you want to say). Be polite. Tell them that you were trying to be safe wearing your lap belt and that you didn't know you had to wear both belts to be legal. Tell them how long you have been using just the lap belt without any comment, warning or ticket in the past. Don't even mention the officer. The judge can write it off or reduce the charge and/or fine. If you can't do the above don't bother to go to court.
