Edward Douglass White, Coffin v. United States (156 U.S. 432…
“ A doubt suggested by the ingenuity of counsel, or by your own ingenuity, not legitimately warranted by the evidence, or the want of it, or one born of a merciful inclination to permit the defendants to escape the penalty of the law, or one prompted by sympathy for them or those connected with them, is not what is meant by a reasonable doubt. A 'reasonable doubt,' as that term is employed in the administration of the criminal law, is an honest, substantial misgiving, generated by the proof, or the want of it. ”
