Fittingly, the most chilling scene in the movie doesn’t take place on a city street, or at a protest, or during a drug raid. It takes place in a conference room. It’s from a police training conference with Dave Grossman, one of the most prolific police trainers in the country. Grossman’s classes teach officers to be less hesitant to use lethal force, urge them to be willing to do it more quickly and teach them how to adopt the mentality of a warrior. Jeronimo Yanez, the Minnesota police officer who shot and killed Philando Castile in July, had attended one of Grossman’s classes called “The Bulletproof Warrior” (though that particular class was taught by Grossman’s business partner, Jim Glennon).

In the class recorded for “Do Not Resist,” Grossman at one point tells his students that the sex they have after they kill another human being will be the best sex of their lives. The room chuckles. But he’s clearly serious. “Both partners are very invested in some very intense sex,” he says. “There’s not a whole lot of perks that come with this job. You find one, relax and enjoy it.”

Grossman closes the class with a (literal) chest-pounding motivational speech that climaxes with Grossman telling the officers to find an overpass overlooking the city they serve. He urges them to look down on their city and know that they’ve made the world a better place. He then urges them to grip the overpass railing, lean forward and “let your cape blow in the wind.” The room gives him a standing ovation.
