Richard Parker, Paul W. Williams Professor of Criminal Justice at Harvard Law School, presents his thoughts on how populism has figured in the study and practice of modern American constitutional law and the effect it has had. Opening and closing his remarks with the rallying cry: 'Power to the People!', Professor Parker recalls his involvement in the 'New Left' in the 1960s, his role as a community organizer, and how his activism led to spells in jail.
