Can anyone make the topic of constitutional interpretation interesting, for non-lawyers? The person I'd put near the top of the list is US Supreme Court Justice Antonin Scalia who has written a 600 page book on the topic entitled, "Reading Law: The Interpretation of Legal Texts".
Here's an interesting interview with him on the topic. He's articulate, intelligence yet understandable, and witty.
A few years ago, I sent him a letter along with a book I was interested in him seeing. I had heard him speak in person shortly before when he said he only read letters if there was money enclosed. So I included $1 with a reminder of his statement. He sent me back a letter with a witty sentence or two rejoinder coupled with a line in Latin. His response fit my impression of him perfectly.
