The 2019 Christchurch terrorist attack was a game changer for law enforcement in New Zealand and beyond. The live stream and subsequent reuploads of the attack garnered millions of views, posing a real risk of encouraging copycat attacks. The Christchurch Call was established in this context, as a collaboration between governments, tech companies, and civil society to ensure that terrorists and violent extremists can never use social media to amplify their attacks again. In this episode of NATO DEEP Dive, Dr. Sajjan Gohel is joined by Paul Ash, the Christchurch Call and Cyber Coordinator in the Department of the Prime Minister and Cabinet in New Zealand to discuss his crucial role in the formation of this initiative.
