In our most recent podcast, Roger Parloff gave us an inside look at the Proud Boys trial which has been underway in the U.S. District Court of the District of Columbia since January 12th. In this follow-up to Mr. Parloff, we asked Dr. Megan Squire, a computer scientist, how she applies data science techniques to track and expose what she calls "networks of hate and extremism" online. She has studied the Proud Boys since 2017. Dr. Squire recently joined the Southern Poverty Law Center to continue her research.
