We have a special treat in this off-cycle episode!  NSA GC Glenn Gerstell is in Austin to speak to our students here at UT, and (no doubt against his better judgment) he agreed to sit for an interview with Professors Chesney and Vladeck.  The conversation focuses in particular on the nature, operation, and criticisms of Section 702 collection authority.  As you probably know, Section 702 is scheduled to expire at the end of December, and there is certain to be a fascinating, high-stakes Congressional fight over its renewal in the months ahead.   Tune in for our discussion of targeting, minimization, "backdoor" searches, database queries, masking, unmasking, and many other key elements in the debate!
