England does not have the Second Amendment. Also, the United States Supreme Court Justice, John Marshall Harlan, in Beard v. United States, 158 U.S. 550, 562, 15 S. Ct. 962, 966, 39 L. Ed. 1086 (1895) stated that:
"The defendant was where he had the right to be, when the deceased advanced upon him in a threatening manner, and with a deadly weapon; and if the accused did not provoke the assault and had at the time reasonable grounds to believe and in good faith believed, that the deceased intended to take his life or do him great bodily harm, he was not obliged to retreat, nor to consider whether he could safely retreat, but was entitled to stand his ground and meet any attack made upon him with a deadly weapon, in such way and with such force as, under all the circumstances, he, at the moment, honestly believed, and had reasonable grounds to believe, was necessary to save his own life or to protect himself from great bodily injury." (my emphasis)
This is why the lower courts, federal and state, that keep quoting District of Columbia v. Heller, 554 U.S. 570, 592, 171 L.Ed 2d 637, 128 S.Ct. 2783 (2008) for the proposition that keeping and bearing arms only applies to the home is without merit.
