The fact that it is a big issue and a controversial and ultra partisan subject thats caselaw will have major political aftershocks is the reason that SCOTUS has been dodging 2A cases one after another. And the ones they do take are intentional lame/mild/freebies so they can go home at night at think they did something about the issues regarding 2A. This is a simple case. It's a violation of Common Use. The real problem is how many of those court justices actually want to say that? Not many from what history says.
