Online Sleuths Relentlessly Track Down Jan. 6 Insurrectionists

Federal attorneys say more than 725 people have now been arrested. But the FBI still seeks help in identifying more.

A year after the U.S. Capitol insurrection, a community of mostly faceless, online sleuths has been poring through images and videos mined from social media. Their mission is to identify rioters like #carharttcowpoke and #cindermagarella. 

John Scott-Railton is a prominent researcher who spurred crowdsourced efforts on Twitter. 

"What happened after January 6 is that the world saw how many people had some skills that they could point to this problem," he said. "For example, there are people who do nothing but think about retro t-shirts. Well it turns out there was a way for somebody like that to help around January 6. There are sneakerheads, people who are obsessed with sneakers. Turns out those people had a way to help."
