Edward Douglass White, Williamson v. United States — Opinion of the Court
“ The exception to the privilege is that it shall not extend to 'treason, felony, or breach of the peace.' These words are the same as those in which the exception to the privilege of Parliament is usually expressed at the common law, and were doubtless borrowed from that source. Now, as all crimes are offenses against the peace, the phrase 'breach of the peace' would seem to extend to all indictable offenses, as well those which are in fact attended with force and violence, as those which are only constructive breaches of the peace of the government, inasmuch as they violate its good order. ”
