Encyclopedia of Ethical Failure

The Office of General Counsel of DOD puts out such an encyclopedia every so often; its latest version was issued in July 2013. It is intended to be used as a training tool. The "goal is to provide DoD personnel with real examples of Federal employees who have intentionally or unwittingly violated the standards of conduct". It's truly a fascinating document. In over 160 pages they list a wide variety of offenses, many of which are simply funny (although the perpetrators of these offenses were punished, sometimes by jail time). The offenses are listed alphabetically from abuse of position to travel violations.
