"...we cannot defend freedom abroad by deserting it at home."

Last night I saw "Good Night, And Good Luck" about Edward R. Murrow's televised battle of words with Senator Joe McCarthy. A very spare, intense but deeply humanistic movie. Terrific performances. But the greates strength of the film is Murrow's own words.
See the movie. Until then here are a couple links to Murrow transcripts:
Murrow's Speech to the RTNDA Convention: ...Our history will be what we make it. And if there are any historians about fifty or a hundred years from now, and there should be preserved the kinescopes for one week of all three networks, they will there find recorded in black and white, or color, evidence of decadence, escapism and insulation from the realities of the world in which we live. I invite your attention to the television schedules of all networks between the hours of 8 and 11 p.m., Eastern Time. Here you will find only fleeting and spasmodic reference to the fact that this nation is in mortal danger. There are, it is true, occasional informative programs presented in that intellectual ghetto on Sunday afternoons. But during the daily peak viewing periods, television in the main insulates us from the realities of the world in which we live. If this state of affairs continues, we may alter an advertising slogan to read: LOOK NOW, PAY LATER.
For surely we shall pay for using this most powerful instrument of communication to insulate the citizenry from the hard and demanding realities which must be faced if we are to survive. I mean the word survive literally.
A Report on Senator Joseph R. McCarthy: ...No one familiar with the history of this country can deny that congressional committees are useful. It is necessary to investigate before legislating, but the line between investigating and persecuting is a very fine one and the junior Senator from Wisconsin has stepped over it repeatedly. His primary achievement has been in confusing the public mind, as between internal and the external threats of Communism. We must not confuse dissent with disloyalty. We must remember always that accusation is not proof and that conviction depends upon evidence and due process of law. We will not walk in fear, one of another. We will not be driven by fear into an age of unreason, if we dig deep in our history and our doctrine, and remember that we are not descended from fearful men -- not from men who feared to write, to speak, to associate and to defend causes that were, for the moment, unpopular.
This is no time for men who oppose Senator McCarthy's methods to keep silent, or for those who approve. We can deny our heritage and our history, but we cannot escape responsibility for the result. There is no way for a citizen of a republic to abdicate his responsibilities. As a nation we have come into our full inheritance at a tender age. We proclaim ourselves, as indeed we are, the defenders of freedom, wherever it continues to exist in the world, but we cannot defend freedom abroad by deserting it at home...
