How is Legitimate Authority Determined in a Democracy?

If law enforcement officers are faced with a conflict between two social groups, a democratic government dictates that the same law, the same interpretation of the law, and the same method of enforcing that law be applied to both parties. Conflict is inevitable in human society. Along with education and cooperation, social disagreement is one of the necessary components in the social engine of positive change. A culture would have to be static, moribund, in stagnation for there to be no societal conflict. There have always been groups who selfishly only look out for their own interests, to the sacrifice of the needs of others. Democracy was conceived to curtail this tendency in human society. Authority in a democracy rests with the entire citizenry, not with a plutocratic body. There is no "rabble" in a democracy -- that is a pejorative word used by autocratic thinkers who have no business governing America. Protest is a core patriotic institution of a democracy, and we have been doing it on this land mass since we were ruled by the British Empire. It has also been the seedbed of reform and improvement of life in this nation for over two centuries. To say that protest is an illegitimate act is to enable a controlling minority to monopolize political action. This is a transgression against the Constitution. If government is only effectively and consistently used to protect a narrow set of interests (e.g., economic parasitism), then it is not a democracy but the return of Medievalism, of hierarchical society, of unequal legal rights and privileges. This current derangement in American government is destroying the dream, the sacrifice, the hard work of our Founding Fathers and their ideological successors. Law enforcement officers confiscating books (like they were weapons or something) from peaceful protestors (who are fed up with the collusion between those corporations seeking omnipotence and members of government seeking pay-offs to give these corporations free passes to trounce the rights of ordinary citizens) is something I never would have thought could occur in a democracy. The impounding of books is what happened in Nazi Germany, is what happens in China to this day. It is disgusting. But the informing and transforming power of the printed word is feared by those who know they do wrong. Notice that the political forces making the police confiscate books are the same set of ones that are amplifying gun rights demanded by segments of society who typically care little for human rights. Ironic, huh? "We the People..." That's all of us right? Just checking...
