State your case in a respectful way and let the chips fall where they may. Tell the judge that the first individual(important: don't say officer) didn't identify himself as a police officer so you didn't understand the gravity of the situation at the time. It wasn't until the second individual identified them self as a police officer that you understood and did what was asked of you. Just tell the truth.
Good luck!
