" This reading is confirmed by the fact that the clause protects only one right, rather than two. It does not describe a right “to keep arms” and a separate right “to bear arms.” Rather, the single right that it does describe is both a duty and a right to have arms available and ready for military service, and to use them for military purposes when necessary.13 Different language surely would have been used to protect nonmilitary use and possession of weapons from regulation if such an intent had played any role in the drafting of the Amendment."

I agree that it doesn't protect things like concealed carry, but it MUST protect the right of individuals to retain firearms within their own homes.
