astonishing amount of perjury in courts of law

"The astonishing amount of perjury in courts of law is a
sad commentary on human veracity. In spite of the oath,
more untruths are probably uttered in court than
anywhere else. This deviation from veracity ranges from
mere exaggeration all the way to vicious perjury. Much of
this untrue testimony grows directly out of human
nature under unusual stress and is not an accurate
measure of truth-speaking general. In order to shield a
friend or help one to win in what is thought to be a just
cause, or because of sympathy for one in trouble, many
members of the frail human family are inclined to violate
the truth in a court of law as they will not do elsewhere."
In the words of Osborn (The problem of proof - Albert S.
Osborn, PP 22, 23, New York, Matthew Bender and Co.
1926 - quoted in (2) ibid, P.226).
