Britta Eder’s list of phone contacts is full of people the German state considers to be criminals. As a defense lawyer in Hamburg, her client list includes anti-fascists, people who campaign against nuclear power, and members of the PKK, a banned militant Kurdish nationalist organization.

For her clients’ sake, she’s used to being cautious on the phone. “When I talk on the phone I always think, maybe I’m not alone,” she says. That self-consciousness even extends to phone calls with her mother.
