The day before, many were appalled to hear the Director of the FBI announce that Hillary Clinton would not be charged for mishandling classified information. The two events may seem unrelated, but at bottom, they concern the same fundamental problem: impunity.

Impunity is the essence of power. What, after all, is power? Is it simply the capacity to exert unjust force? The ability to impress one's will upon the flesh or belongings of another? No, it's more than that.

Most anyone can wield unjust force. Anyone could walk out onto the street right now and exert their will on somebody weaker: say, pushing over an old lady or stealing candy from a baby. And the toughest, or most heavily-armed guy in town can strong-arm just about any other single person.

But isolated incidents of aggression do not constitute power. The "reign" of the rogue rampager is generally short-lived. It only lasts until the community recognizes him as the menace to society that he is and neutralizes him.
