English Common Law, which is the basis for the system of law in the United States (except for Louisiana which relies on the Napoleonic Code - and - Common Law) holds that "a man's home is his castle". Being a sovereign individual allows the citizen personal freedom of choice as opposed to collective mandates. One test of whether individuals are allowed that sovereignty is their right to use reasonable means to protect themselves from others. We all know that the government (any government) itself is incapable of protecting its population from crime. The police can respond, take reports and take action AFTER a crime has occurred, but that's never quite enough. The primary responsibility to protect you (and your family) falls... on you.
