Justices Scalia and Breyer recently sat down with Jan Crawford Greenburg to discuss constitutional interpretation and the role of the Supreme Court. You can watch a video of the 90-minute event here. I've watched just a few minutes of it so far, and what I have seen is excellent. Both Justices have made these points before, but I suspect a lot of people will find this discussion a fantastic introduction to debates on constitutional interpretation. Check it out.
