I developed a deep sadness for celebrities, a pity that they often are caught in a plastic world that runs too hard and too fast, and that many times that world means destroyed relationships with everyone they know and love.
I would say that the Pentagon Papers case of 1971 - in which the government tried to block the The New York Times and The Washington Post that they obtained from a secret study of how we got involved in the war in Vietnam - that is probably the most important case.
