Whether it's Milo Yiannopoulos being unable to speak at Berkeley or James Damore being fired for his Google memo, freedom of speech has repeatedly emerged as a topic of controversy, especially in terms of hate speech. In this episode of Planet Lex, host Daniel Rodriguez talks to Marty Redish, a freedom of expression professor, about how the law defines free speech and the right of various institutions, like businesses and universities, to regulate speech. They also discuss what is and isn't protected by the first amendment, including the defense of hate speech.

Martin H. Redish, the Louis and Harriet Ancel Professor of Law and Public Policy at Northwestern Pritzker School of Law, teaches and writes on the subjects of federal jurisdiction, civil procedure, freedom of expression and constitutional law.
