"They came first for

Kurtz, And I didn’t speak up because I wasn’t an investigative reporter;
And then they came for Fredesso, And I didn’t speak up because I wasn’t an author;
And then they came for Joe the Plumber, And I didn’t speak up because I wasn’t a plumber;
And then . . . they came for me . . . And by that time there was no one left to speak up."
