School violence researcher and Homeland Security expert David Riedman joins Steve and Jesse to break down the radicalization pipeline feeding modern school shootings. David covers how isolated kids get pulled into nihilistic violence through deregulated social media, grooming on Roblox, and private Discord servers, and why your BJJ gym might be one of the most powerful interventions available.
