"A fundamental principle of our government is that a well-informed citizenry can take part in the important decisions that set the present and future course of the nation. Our Founding Fathers provided in the Constitution and in the Bill of Rights freedoms for all Americans, many of which are promoted by open access to information . . .
Numerous acts of Congress, including the Freedom of Information Act, are intended to further this principle. Most Americans, having never known any other way of life, take for granted open access to information about their Federal, State, and local governments. They also understand that some secrecy is necessary to protect both national security and the right to privacy."
