Of course it won't. Not directly anyway. The court itself posed the Question to be answered.
Whether the following provisions - D.C. Code §§ 7-2502.02(a)(4), 22-4504(a), and 7-2507.02 - violate the Second Amendment rights of individuals who are not affiliated with any state-regulated militia, but who wish to keep handguns and other firearms for private use in their homes?
There will be three answers, one for each section of the DC code, yes or no. However their rational will be important. If they find the answer is "yes" for even a single one of those, it will almost certainly be because they've determine the right is individual, belonging to indivduals not necessarily part of any state-regulated militia.
That of course will trigge a whole bunch of other cases challenging this or that gun law, federal, state and local.
By "a whole bunch" you mean in all those states where they currently don't allow handguns and other firearms for private use in homes".
I understand that you don't have the time to list the entire "bunch", but maybe you can list one state that doesn't currently allow this?
