Bolsheviks and Nazis alike practiced collective punishment. The Reds would take hostages against “good behavior” of residents of a town and shoot them if any resistance was offered. Nazis would sometimes kill everyone in a town near which one of their troops perished. We look at such practices with abhorrence, though US and Allied bombings probably killed a few innocent bystanders of their own. As a culture, we don’t view collective punishments as acceptable…or do we?

What is the point of rules that are not enforced?
