The shutdown is not really about government authority or government police power or removal of our freedoms. Not when we consent.
It only works if the people consent to the exercise of authority which we do during exigent circumstances because we accept the government intrusion as being in our best interests. When we no longer consent to the intrusion, the government authority or “police power” becomes unenforceable.
Even in everyday life, we consent to government intrusions. Notwithstanding court decision, we accept warrantless searches of our persons and belongings when we enter an airport or a ballgame. We consent because we appreciate the greater safety concerns. But, there are boundaries. If security officers started rifling through our wallets on orders of the government, the people wouldn’t allow it.
In America, the power is always with the people when it comes to our freedoms. The government (on all levels) may intrude at times on our freedoms, but in reality, it is only with our consent.
