As ICE cracks down in Minneapolis and across the country, reporters and privacy advocates have drawn attention to how the agency is using technology: scanning people’s faces without consent, using private health records to make arrests, tracking people’s location in real time with phone data.
So how does all this work? How does the United States’ data ecosystem make it possible for not just ICE, but any number of government agencies and businesses to buy our private data? And what actually happens after we send that DM or open up Instagram at a protest to post a picture?
To learn more, Host Flora Lichtman sits down with law professor and tech policy expert Laura Moy. She’s testified in Congress about privacy laws and how data brokers profit off of personal data.
Guest: Laura Moy is an associate professor of law at Georgetown Law, based in Washington, D.C.

Point systems are everywhere. Ready for movie night? Consult Rotten Tomatoes. Vetting a new pediatrician? See how many stars they have. At work, it can be even more pervasive: There’s KPIs and ROIs because success has to be measurable.  
But what happens when we boil something down to one nice number? What do we lose? Philosopher C. Thi Nguyen, author of the new book The Score, joins Host Flora Lichtman to explore how metrics can be soul-crushing in work and in life, yet keeping score is freeing in the world of games.
