We never have and never will get a decision out of the courts that is so broad in it’s scope as to fully restore our gun rights in one fell swoop. What this decision did was two very important things:
(1) Confirm that the Second Amendment right to keep and bear arms is a right is an individual right separate from any militia qualification.
(2) Give us a judgement from which to build future cases upon.
The practical implication as of this moment is that simply the most egregrious law in the country in DC has been stricken on a Second Amendment basis. Citizens living in DC had zero gun rights a week ago. They now have some.
What you seem to forget is that there is a political dimension to gun rights. The fact that you can carry a concealed firearm in Alaska without a license is a reflection of a political decision. Now that this court case has come about, the Alaska state legislature is not going to go back and say “well gee, this decision allows us to restrict the right to carry so we’re going to do that.” Their law will remain unchanged because politically speaking, the people in Alaska like their law just fine. There is also the issue of state Constitutions which are often far more explicit in their protection of gun rights than the Federal Constitution is.
You are correct in noting that the anti’s will selectively use portions of this case to try to justify gun restrictions. Then again, they would also seek to use the fact that the sun rises in the east and sets in the west as justification for gun restrictions. They’re gun grabbers and that’s just what gun grabbers do.
In states like New Jersey, there are already widespread restrictions on carry. This ruling will eventually force that state to justify those restrictions against a judicial standard, which is something they did not have to do previously. We will probably never have as expansive a set a gun rights in New Jersey as we will in Alaska or Arizona or Idaho or Virginia. But folks in New Jersey will at least have a baseline set of gun rights.
Excellent summary.
