Clearly, that recognition and protection seems to be slipping away.
D.C. v Keller (the right to bear within ones home, limited to federal enclaves) was a 5/4 decision.
McDonald v. Chicago, which extended within the home to the states, was a 5/4 decision.
Those are close calls under any view.
just about anything that upholds the constitution is a 5-4 decision these days. not good.
