"A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed."
诠释成现代非省略式应该是这样:
主句:A well regulated Militia shall not be infringed.
修饰句:(Such a Militia is considered) being necessary to the security of a free State, (and to) the right of the people to keep and bear Arms.
不是让老百姓拥枪,而是每州严格管理的民兵组织可以代表老百姓拥枪。
