Every day, we generate tons of digital exhaust: our web browsing, GPS location, online and in-store purchases, emails and messages, social media posts and feed viewing habits, and much, much more. Online marketers and data brokers have been living off these breadcrumbs for years. The intelligence and law enforcement agencies have found this data to be incredibly revealing, and they can buy most of this data on the open market without requiring any sort of warrant - and they have. This has important implications for democratic societies that value privacy and freedom. I'll discuss how this mass surveillance works and what it means for all of us with Byron Tau, author of the book "Means of Control".
