Opinion: Can federal or state law ban assault-style rifles?

The recent Supreme Court decision in New York State Rifle & Pistol Ass’n was aimed at a citizen’s right to carry a concealed handgun, or more aptly, the ability of a state to require a showing of cause or real apprehended danger before issuing a license to carry in public.  In essence, the court held a citizen must be permitted to carry a gun for defense outside the home—concealed or open carry must be allowed.  One or the other must be permitted; both modes of carry cannot be prohibited.
