True, LtS. Your other point was a good one, too. I met a man, once, who had an ID number on his forearm from being a prisoner in Germany during WWII. It was quite an oddity in our little corner of Colorado in those days.(I was about thirteen.) I remember he had a strong accent and there were some people who thought, cynically or not, he may have been a Nazi who had it put on, post-war, to cover his tracks, so to speak.
