Judge Jeffrey S. Sutton, of the U.S. Court of Appeals for the Sixth Circuit and author of the new book, 51 Imperfect Solutions: States and the Making of American Constitutional Law, explores four constitutional debates — school funding, the exclusionary rule, eugenics, and mandatory flag salutes — to shed light on the importance of state courts and state constitutions in protecting liberty. Jeffrey Rosen, president and CEO of the National Constitution Center, moderates.
