Can a Camera on Every Corner Make Us Safer? | Garrett Langley | TED

Sobre este vídeo

Garrett Langley founded Flock because of a basic frustration: it was too easy to get away with crime in the US. His solution — a network of license plate readers, cameras, drones and audio sensors — has changed how police departments investigate crime, while also raising urgent questions about safety, surveillance and privacy. In this talk, Langley addresses the controversy around this widely debated technology and makes the case for why it will make the world safer.
