Edward Snowden. Quote from Permanent Record

WHENEVER I GO outside, I try to change my appearance a bit. Maybe I get rid of my beard, maybe I wear different glasses. I never liked the cold until I realized that a hat and scarf provide the world's most convenient and inconspicuous anonymity. I change the rhythm and pace of my walk, and, contrary to the sage advice of my mother, I look away from traffic when crossing the street, which is why I've never been caught on any of the car dashcams that are ubiquitous here. Passing buildings equipped with CCTV I keep my head down, so that no one will see me as I'm usually seen online - head-on. I used to worry about the bus and metro, but nowadays everybody's too busy staring at their phones to give me a second glance. If I take a cab, I'll have it pick me up at a bus or metro stop a few blocks away from where I live and drop me off at an address a few blocks away from where I'm going.
