                                        As quoted in The Unlawful Concert : An Account of the Presidio Mutiny Case (1970) by Fred Gardner. 
Unsourced French: Il suffit d'ajouter "militaire" à un mot pour lui faire perdre sa signification. Ainsi la justice militaire n'est pas la justice, la musique militaire n'est pas la musique. 
It suffices to add "military" to a word for it to lose its meaning. Military justice is to justice what military music is to music.
