Show Notes
Byron Tau is a Pulitzer Prize-winning investigative reporter at ProPublica and the author of "Means of Control." He spent five years tracing how the surveillance apparatus built after 9/11 came home and found Border Patrol monitoring millions of American drivers through hidden cameras and a secret algorithm. Shawn and Byron get into who built these tools, how buying data legally sidesteps the Fourth Amendment, and what it means when the machinery aimed at foreign targets gets turned around.
Privacy Isn't Paranoia. It's Protection.
