When is speech no longer just speech? After Charlottesville, the Limits of Free Speech

'When is speech no longer just speech? David Remnick looks at how leftist protests at Berkeley, right-wing violence in Charlottesville, and open-carry laws around the country are testing the traditional liberal consensus on freedom of expression. He speaks with Mark Bray, the author of a new and sympathetic book about Antifa; Melissa Murray, a law-school professor at U.C. Berkeley; and Dahlia Lithwick, a legal analyst for Slate.' -- The New Yorker Radio Hour
