The idea of protecting everyone all of the time is often the "wedge" that is used to start the totalitarian states.
Can you name one where this was true? In Nazi Germany, the Soviet Union and China, political control and ideological purity were the motivation and the wedge.
There was also the idea that the police control was acceptable because they would protect everyone, and that was "why" they needed extrodinary powers. No government comes into control without some reason to placate the people, unless it is a foreign invasion. And some times even then. After all, the people outnumber the government "want-to-be's".
