Professor Jeff Kosseff, author of "Liar in a Crowded Theater: Freedom of Speech in a World of Misinformation" examines and defends constitutional protection for false speech. "It's the listener and the reader who gets to choose, not the Government!" says Jeff. His warning is that "Once we give away our freedom of speech, we are unlikely to get it back." Jeff is also the author of "The United States of Anonymous: How the First Amendment Shaped Online Speech" and "The Twenty-Six Words That Created the Internet."
