 One response to this is to distinguish public corruption from private corruption, and to argue that the above definition is a definition only of public corruption. But if ordinary citizens lie when they give testimony in court, this is corruption; it is corruption of the criminal justice system. However, it does not involve abuse of a public office by a public official. And when police fabricate evidence out of a misplaced sense of justice, this is corruption of a public office, but not for private gain.
