This morning, I did an hour-long show for Minnesota Public Radio on “the meaning of liberty, and how it has changed since the U.S. Constitution was framed.” It is a wonderful luxury to have a whole hour to elaborate one’s views, but even so I can think of so many things I wish I had said. One gets sidetracked by the thrust of the questions of the host, and of the callers. But all-and-all, I think it is worth listening to here. (Unfortunately, you need RealAudio to open the stream)
