Our government's purpose is not only to represent the peoples of each of its member states/counties/municipalities as accurately as possible, but to always do so with the understanding that we are a nation based upon individual liberties. Potential infringements upon individual liberties absolutely must
be weighed and thoroughly understood. Strictly speaking, we handle that by authorizing our government only a limited number of powers, as delineated in our national and state constitutions. If it's not a power defined in said constitutions, it is not a power lawfully possessed by the government body. For better or worse, that is the law of this land. (I am of the opinion that it is for the better; given how poorly our current governing officials understand this, I'd rather not think of how they may behave without such restrictions).
