Retired FBI special agent Scott Payne spent 28 years infiltrating some of America's most dangerous organizations—from motorcycle gangs and cartels to white supremacist accelerationist groups. In this sprawling conversation, Payne recounts his seven-month infiltration of a neo-Nazi cell planning violence, his two-year undercover operation with the Outlaws motorcycle club, and the psychological toll of living double lives while building genuine friendships with criminals he was betraying. FBI undercover work requires stress inoculation training and repetitive drills because adrenaline and auditory exclusion prevent officers from remembering their actions during high-threat situations.
