   We are a democracy, and there is only one way to get a democracy on its feet in the matter of its individual, its social, its municipal, its State, its National conduct, and that is by keeping the public informed about what is going on.There isnot a crime, there isnot a dodge, there is not a trick, there is not a swindle, there is not a vice which does not live by secrecy.Get these things out in the open, describe them, attack them, ridicule them in the press, and sooner or later public opinion will sweep them away.

-Pulitzer,Joseph
c.1910  Quoted in Alleyne Ireland An Adventure with a Genius, ch.4.

Secrecy is the first essential in the affairs of State.
