Very interesting story. You stated that the Officer became wide-eyed after viewing. You also claim that he continued to sit along the roadside after you pulled off. It very well may be, that he himself carried a Red Card. However, could it be, that he was raised on an unhealthy diet of Christian frightfests. Perhaps he became so terrified upon viewing your Red Card, he considered it within his best interests to get you long gone. Either way, your Red Card saved the day.
