"I thought at the time and still think that the Nuremberg
trials were unprincipled. Law was created ex post facto to
suit the passion and clamor of the time. The concept of ex post
facto law is not congenial to the Anglo-American viewpoint on
law. Before criminal penalties can be imposed there must be fair
warning that the conduct which one undertook was criminal."
William O. Douglas, LL.D. (Associate Justice, Supreme
Court of the U.S., 1939-1975)
