For years, and especially in the past year, far-right groups have used social platforms like Twitter and Facebook to organize violent movements. On Wednesday, once again, we saw the results of that online organization lead to real-life violence with an armed insurrection at the U.S. Capitol. In response, Facebook and Twitter removed posts by President Donald Trump that seemed to encourage the mob, and locked Trump’s accounts on both platforms. Facebook and Instagram started blocking hashtags related to the attack on the Capitol, and Facebook said it would also scan posts for mentions of bringing weapons to any location, in or outside Washington. Molly speaks with Joan Donovan, research director of the Shorenstein Center on Media, Politics and Public Policy at Harvard Kennedy School. She said Wednesday that an event like the Capitol assault, though, felt almost inevitable.
