“A half-truth is the most cowardly of lies.”

Concerning right-wing radio shortly before the 2004 U.S. Presidential Election, in NOW (17 December 2004) http://www.pbs.org/now/transcript/transcript351_full.html
Context: On the eve of the election last month my wife Judith and I were driving home late in the afternoon and turned on the radio for the traffic and weather. What we instantly got was a freak show of political pornography: lies, distortions, and half-truths — half-truths being perhaps the blackest of all lies. They paraded before us as informed opinion.
