One of my favorite exchanges from yesterday's oral arguments

I found this quite amusing:

CHIEF JUSTICE ROBERTS: So if you have a law that prohibits the possession of books, it's all right if you allow the possession of newspapers?
MR. DELLINGER: No, it's not, and the difference is quite clear. If -- if you -- there is no limit to the public discourse. If there is an individual right to guns for personal use, it's to carry out a purpose, like protecting the home. You could not, for example, say that no one may have more than 50 books. But a law that said no one may possess more than 50 guns would -- would in fact be I think quite reasonable.
CHIEF JUSTICE ROBERTS: The regulation -- the regulation at issue here is not one that goes to the number of guns. It goes to the specific type. And I understood your argument to be in your brief that because rifles and shotguns are not banned to the staple extent as handguns, it's all right to ban handguns.
