Airs Sunday, January 4 at 6 p.m. Some say that indiscriminate collection of U.S. phone records is a gross invasion of privacy.  Others say that it is necessary to keep us safe.  But what does the U.S Constitution say?  Is collection of phone records a “search” or “seizure?"  If so, is it “unreasonable?"  Does it require a particularized warrant and probable cause?  These are among the most consequential — and controversial — constitutional questions of our time.  Arguing for the motion are Alex Abdo, Staff Attorney for the ACLU's Speech, Privacy and Technology Project; and Elizabeth Wydra, Chief Counsel for the Constitutional Accountability Center. Arguing against the motion are: Stewart Baker, Former Assistant Secretary for Homeland Security & Former General Counsel for the NSA; and John Yoo, a Professor of Law at UC Berkeley & Former Justice Department Lawyer.

Airs Sunday, February 23 at 6 p.m. The NSA collects data on billions of phone calls and internet communications per day. Are these surveillance programs legal? Do they keep us safe? What tradeoffs are we willing to make between security and privacy? As Benjamin Franklin might have asked, "Are we giving up essential liberty to purchase temporary safety, and thus deserving of neither?"
