Comet Ping Pong and the Pizzagate armed incident

Comet Ping Pong, a pizzeria in northwest Washington, D.C., was the focus of the internet-fueled 'Pizzagate' conspiracy in 2016. On December 4, 2016, an armed man entered the restaurant and fired a weapon while attempting to investigate the false online claims; no one was physically injured and the suspect was arrested. The incident is widely cited in reporting and academic discussion as an example of real-world harm stemming from viral online misinformation.
