Pro-Palestinian students interrupted a dinner held by a top free speech defender at Berkeley. A polarized and very public controversy has followed

During a dinner for students that the dean of the University of California, Berkeley law school held in his house’s backyard earlier this month, a woman wearing a hijab and checkered Palestinian scarf suddenly stood up with a microphone and amplifier. What followed lasted only a couple of minutes, but has led to a fierce debate about the limits of free speech, drew death threats to those involved, and created a “media firestorm,” as the dean, Erwin Chemerinsky, has put it.

Some short and chaotic viral videos illustrate part of what happened. One of them shows the woman, Malak Afaneh, as she gives a Ramadan greeting; she is accompanied by a small group of other student protesters. As Afaneh begins reading a speech about the Israel-Gaza war, Chemerinsky and his wife, the law professor Catherine Fisk, quickly cut Afaneh off.
