The Second Amendment was based partially on the right to keep and bear arms in English common-law and was influenced by the English Bill of Rights of 1689. Sir William Blackstone described this right as an auxiliary right, supporting the natural rights of self-defense, resistance to oppression, and the civic duty to act in concert in defense of the state.
Excellent post. Ironically they chose to do away with this right of self-defense and we see what happened there. This should be an inspiration to the people of the United States to keep our Second Amendment strong in the interest of our freedom.
