"Joshua Fisher-Birch, a researcher at the nonprofit Counter Extremism Project, said the rise of terrorist violence performed online can’t be blamed on any one technology. But the power that a video-sharing platform gives users, to broadcast live to the world, can still have consequences that are too devastating to ignore. 'When someone commits an act of violence like this, they’re speaking to this community that idealizes these extremist mass shooters. There’s a group of people they want to impress,' Fisher-Birch said. 'Live-streaming turns that act of violence into a spectacle, … this simultaneously public and intimate act.' For violent extremists, he added, the technology 'has turned mass shootings like these into propaganda gold mines.'"
