“We do think that law and public policy can play a constructive, albeit limited, role in protecting not only public health and safety but public morals as well.”

If by limited, you mean very limited, I disagree entirely. And also how limited depends on what you mean by “law and public policy.”

Education is a powerful tool, one of the most powerful ones available to build awareness and conscientious attitudes in people. The impact education has on public health, safety, and morals is profound. Obviously, everything then hinges on the tool: what education? Which laws and public policies?
