Dear Customer (name blocked for privacy)
There, of couse, is no written "law" granting an individual the "right to break a law" However, if you opt to go to court on the ticket you can offer your "mitigating" circumstances as a defense. You should be able to support your actions with witnesses and other documentation. A trier of fact will take all mitigation factors into consideration - if nothing else, you could walk away with just a fine and no points.
