Not a goof yet listed as such

In the "Goofs" section:
"It was routine policy in the Third Reich to send captured Jewish enemy soldiers to extermination camps. This being the case, it's rather implausible that one of the prisoners in Stalag 17 is named Shapiro." In fact, at least as far as Jewish soldiers in the US, British and Canadian forces were concerned, being captured did not mean being sent to an extermination camp, because the Geneva Convention protected them. So someone from these armed forces with a typically Jewish name would not necessarily be on the way to Auschwitz if captured by the Germans. The Polish Jewish father of Art Spiegelman was captured by the Germans in 1939, and noted that international conventions like the Geneva Convention gave a little protection even to Jewish soldiers in the Polish army, but he narrowly escaped being shot with others when he was discharged and allowed to return home, because civilian Jews lost the protection of these conventions.
