Sorry if I was condescending...
If DC (Not the FedGov), lets this stand, their gun laws get gutted.
If they appeal En Banc and lose, their gun laws are gutted.
If they appeal to the USSC, and the court refuses it, their gun laws are gutted.
If they go En Banc and win, the claimants appeal to the USSC. At this point, if the USSC refuses, we lose.
If they go to the USSC, and win, we lose.
Or, it goes to the USSC, and we win.
I dunno, but I expect it ain't over.
No biggie. I was unclear in my original post. Your comment was understandable.
You're right about FedGov being in a fairly no-win position, but I have faith that the enrobed ones will find a way to duck the issue (like they always do), and Fedgov sure as hell isn't going to enforce it.
