The WSJ had two good articles on this. Having read the opinions, I agree w the WSJ take:
-The dissenting 4 made it clear as soon as they have a 5, Heller and McDonald are history, stare decisis be damned.
-Thomas's concuring opinion may have resurected the P&I clause. It took 20 yrs for "diversity" to make it's way from a concuring opinion to a majority opinion re affirmative action, we can hope the P&I clause does the same for gun rights.
It all depends on who picks the inevitable replacements for the 5?
If Chicago (and others) requires liability insurance, could indirectly boost NRA membership if owners join to get the insurance discount? Millions more buying insurance could lower the cost for the rest of us who are already buying it too?
