Since nearly all the rest have, it's just a matter of time until the 2nd is. Stanley knew he would be convicted, and fully expects to appeal the case until SCOTUS incorporates the 2nd, either by his case or someone else's (before they get to his).
If other parts of the Bill Of Rights have been incorporated by SCOTUS, why won't the 2nd? Remember, there was a time when the others weren't, but now they are.
Wrong.
