One of the hallmarks of a strong society is its ability to smoothly effect change. New leaders and policies, crises and confrontations are all dealt with in an orderly fashion without the threat of violence. New ideas are incorporated within the existing structure. It is a process of evolution, as opposed to revolution. 

Sefer Bamidbar can be viewed as a book of missed opportunities. A small group of Jewish slaves—the midrash claims no more than one in five—showed great faith and resolve as they marched through a barren desert to hear the word of G-d. Under the leadership of Moshe, Miriam and Aharon, they were preparing to enter the land of Israel and thus Sefer Bamidbar opens with the counting of the soldiers who would triumphantly conquer the land. 

In order to be effective, leaders must be sensitive to the feelings and concerns of the general populace. It is not only fact, but also perception that matters. Leaders must have higher ethical standards, and they must also be seen by the public in this light. Any perception (especially if it's true!) that they are above the law renders their moral leadership compromised.
