Allen v. United States (157 U.S. 675…
“ The instruction was that using a deadly weapon, not previously selected with a purpose to use it, was, when used in circumstances of the kind shown, a case of manslaughter. Thus there was a necessary implication that if the pistol had been previously procured, with a view to using it in self-defense, the defendant would be guilty of murder, if he discharged the pistol with fatal effect, even while defending himself from an attack threatening his life. ”
