Is intense questioning justifiable according to Hobbes, Locke, Rousseau and Mill?

Would the scenario of a government using intense questioning on its citizens be justifiable according to Hobbes, Locke, Rousseau and Mill and their state of nature and social contract philosophies?

Suppose a govt. passes a law that requires every citizen to go through intense questioning, probing every aspects of our lives to make society more safe and to protect our freedoms. What would Hobbes, Locke, Rousseau and Mill say about this?

Hobbes would say thay as long as you are not chained you are still free as a bird.
Locke would say that the government is the agent of the people and so it has to perform exactly as citizens expect.
Rousseau was a preponent of positive freedom and, according to him, you should be forced to be free. He advocated censors and civil religion to encourage citizens to think in a certain way.
Mill would say that the only reason for the government may interefere with your actions would be to prevent harm to others.
