France and NZ initiative to curb violent extremism: "How far are tech companies willing to go?"

France24's Douglas Herbert talks about how French President Macron and New Zealand's PM Ardern are hosting other world leaders and tech chiefs in Paris today as they are launching an ambitious new initiative aimed at eliminating terrorist and violent extremist content on social media and other online platforms. The movement is called the Christchurch Call in name of the New Zealand city that was rocked by a terror attack in March that was partly live-streamed on Facebook.
