Offscreen Narrator: But the word that very few spoke, and the word with perhaps the greatest truth, was the word "prejudice". And most of the United States knew there was prejudice and wanted it to end. But even as the signs came down, the prejudice did not end.
Offscreen Narrator: And it was true the President was killed. But it was also true that the assassin missed his target, for he wanted John Kennedy to die, and that he was unable to do. For no man can take away years of lightning with a single day of drums.
