Laura Jane Grace is guiding me through the discography of beloved UK anarchist punks Crass when security interrupts us. A chocolate Lab starts to sniff around the curtains and scattered Christmas lights that decorate a dressing room in downtown Des Moines, Iowa’s Wells Fargo Arena, where Grace’s band Against Me! will be playing in a few hours. “This is the daily dog sweep,” she explains with a shrug. “2017.” After a few minutes, man and beast leave the room, but Grace is still annoyed by the intrusion. “It’s like that scene in Minority Report where we’re having a conversation, and then all of a sudden our hands are against the wall,” she says. “Talk about your civil rights being taken away.”
