In November 2021, a teenager in rural Texas downloaded the video game Call of Duty: Modern Warfare and quickly became obsessed. He began to research weapons from the game, including a military-grade assault rifle. The company that manufactures the weapon used Instagram to market it. The teenager spent hours on Instagram, using 20 different accounts to browse the app. He learned more about the gun, and saved every dollar he could to pre-order it. 23 minutes after he turned 18 years old, he purchased the weapon. A few days later, on May 24, 2022, the teenager walked into Robb Elementary School in Uvalde, Texas, and used the gun to kill 19 fourth-graders and two teachers.  Now, two years after the massacre, the families of those killed are suing Instagram and Activision Blizzard, the company that publishes Call of Duty. The novel lawsuit faces many legal hurdles – among them is Section 230, a federal law which significantly shields social media companies from liability for third-party content posted on their platforms. How might this long shot lawsuit impact who can be held responsible for mass shootings? And what are its potential implications for Silicon Valley in other contexts?  Joining the show to discuss the case and its potential impact on legal efforts to hold social media companies liable through the court system is Paul Barrett.  Paul is the deputy director and senior research scholar at the NYU Stern Center for Business and Human Rights.Show Notes: Paul M.
