From Marcus Gray's It Crawled From The South:
"...the spoken-word middle eight, lifted from a McCarthy
documentary the band watched during the album's mixing stage. The
film, Point of Order, takes as its climax a key moment during the
televised army-McCarthy hearings of 1954 (the Senator was engaged
in trying to root out subversives in the armed forces). "On
June 9th, McCarthy repeatedly tried to ruin, by associating him
with a left wing group, a young law associate of the Army counsel
Joseph N. Welch. The associate was not involved in the hearings,
and Welch replied to McCarthy's irrelevant and spiteful harangues
thus: 'Let us not assassinate this lad further, Senator. You have
done enough. Have you no sense of decency, sir? At long last,
have you no sense of decency?'"
