John Roberts isn't worried about court ethics, just don't be rude!

Get ready for this one: The Supreme Court doesn’t have a legitimacy problem, Chief Justice John Roberts claimed in a speech this week. No, the most serious threat to the institution as far as he’s concerned is an American public that demands accountability from the courts.

Speaking at the American Law Institute on Tuesday, Roberts said that the “hardest decision” he has had to make while helming the court wasn’t about any core constitutional question—the First Amendment or the death penalty or the separation of powers—but how to protect the justices from a public that’s exercising free speech against the court.

“Judges heckled and shouted down at a law school, protesters outside the homes of justices to the extent that martial protection is needed 24/7,” Roberts bemoaned. That law school heckling? The judge was ​​Stuart Kyle Duncan, an ultraconservative Donald Trump appointee brought to campus by the Federalist Society chapter of Stanford University Law School. The whole event was apparently set up just to create this conflict.

Duncan came prepared, striding into the room with his camera out to film the event so he could “make a record” of their demonstration. After an administrator and a student leader quieted the protesters, the judge skipped his speech and moved directly to Q&A. He then insulted various students (“you are an appalling idiot,” the judge told one) while refusing to engage with their questions. After departing, the judge embarked upon a conservative media tour, declaring that the “coddled law students” behaved like “dogshit” and urging Stanford to discipline them.
