UChicago Law professor Geoffrey Stone has an intimate knowledge of the Supreme Court.

From his time as a law clerk for Supreme Court Justice William J. Brennan where he witnessed the decision Roe v. Wade firsthand, to his decades writing on issues of free speech, to helping shape the University of Chicago’s own policy on free expression, Stone is an expert when it comes to the First Amendment.

But in all his years studying the highest court in the United States, Stone says he has never been more pessimistic for where the judiciary branch is headed.

Stone discusses the current state of the court, the forgotten history of Roe v. Wade, and free speech on college campuses on this episode of Big Brains.
