The Second Amendment is long overdue for a clarifying SCOTUS ruling, one way or the other. The legal "meaning" of that amendment has, if you'll pardon the pun, hung fire for far too long in the courts (though it's perfectly clear to me). Now there is a conflict between two federal circuits--the Supreme Court almost has to step in. If a majority of the court rules correctly on a Second Amendment issue--i.e., for the "individual right" that the amendment plainly confers on citizens--then the precedent has been set, and the gun control movement is out of business for the foreseeable future.
A slightly favorable thing about Roberts is that he did say the Miller court side stepped the individual vs. collective right issue. The gun grabbers have long been saying Miller stood for the collective right interpretation of the Second Amendment.
I agree, let's overturn all these unconstitutional state and local restrictions on ownership and concealed carry.
