@Oddthinking: I've updated my answer to address your comment. I should note that
all legal systems require at least two elements: 1. rules and 2. enforcement. The rules give authorities the power to enforce society's morals in certain ways, but they rarely
compel enforcement. In fact, most legal systems have several layers of human judgement between the law and the consequences of the law. Likely the rule was used, but we can expect it was used to produce justice, not injustice. I think you are underselling the actual claim being made by the chart. —
