Taking a comic seriously, CNN opts to focus on what it does best: news

The beginning of the end of Sen. Joseph McCarthy's hunt for Communists in government came on June 9, 1954, in the Army-McCarthy hearings in Congress. The senator and the Army had come into conflict over the service of G. David Schine, a lawyer on McCarthy's staff who had been drafted. McCarthy and another of his attorneys, Roy Cohn, attempted to have Schine released from Army service so he could return to Washington. The contest of wills eventually became so intense that it resulted in 36 days of congressional hearings broadcast live on national television. The Army was represented at the hearings by Joseph Welch, an attorney from the Boston firm of Hale and Dorr. As Welch was cross-examining Cohn, McCarthy tried to impugn the integrity of Fred Fisher, a young attorney for Hale and Dorr who was not working on the Army case. Welch's objection to the tactic became famous:

Welch: I meant to do you no personal injury and if I did, I beg your pardon. Let us not assassinate this lad further, Senator. You've done enough. Have you no sense of decency, sir? At long last, have you left no sense of decency?
