Well, maybe but probably not. Scalia is not a hinter. He would have outright said that if that is what he meant.
I agree, a hinter he definitely is NOT. This is scathing to say the very least; “I would hide my head in a bag. The Supreme Court of the United States has descended from the disciplined legal reasoning of John Marshall and Joseph Story to the mystical aphorisms of the fortune cookie.”
That, I would guess, is the equivalent of a redneck type such as myself asking, “What in the flying f*** is goin’ on here, this is not the supreme court of San Francisco, dammit!”
