William O. Douglas,
Whitehill v. Elkins — Opinion of the Court
“ Would a member of a group that was out to overthrow the Government by force or violence be engaged in that attempt 'in one way or another' within the meaning of the oath, even though he was ignorant of the real aims of the group and wholly innocent of any illicit purpose? We do not know; nor could a prospective employee know, save as he risked a prosecution for perjury. ”
