Public safety refers to the safeguarding of citizens' well-being and the stability of society through legal, administrative, or communal actions. From John Marshall Harlan’s assertion of state authority to protect public security through legislation to Émile Zola’s focus on governmental duty in maintaining it, the theme has been examined through legal, political, and ethical perspectives.
The President of the United States connected it to community trust, while Hector MacQuarrie emphasized its structural aspects. These viewpoints together highlight public safety as both a legal system and an evolving societal necessity, balancing protection with the common good.
