Experts are calling for a broader discussion around livestreams after a white gunman killed 10 Black people at a Buffalo supermarket. The self-described white supremacist mounted a GoPro camera to his helmet to stream his assault live on Twitch, the video game streaming platform. Twitch and other sites like Twitter and Facebook have learned painful lessons from dealing with the violent videos that now often accompany such shootings. Experts are discussing whether livestreams should exist at all, since once such videos go online, they’re almost impossible to erase completely.
