take his life, is treason. In England, to imagine or compass the
death of the king, or of the queen consort, or of the heir apparent
to the crown, is high treason, as are many other offenses created by
statute. In the United States, treason is confined to the actual
levying of war against the United States, or to an adhering to their
enemies, giving them aid and comfort.
