The Federalist Society has this podcast by yours truly on the oral argument in Salinas v. Texas last week.  The capsule description of the case is:

On April 17, 2013, the Supreme Court heard oral argument in Salinas v. Texas. This case considers whether, when a suspect is silent in response to a single question during a voluntary interview with police before he has been arrested or read his Miranda rights, use of that silence at trial violates the Self-Incrimination Clause of the Fifth Amendment.
