I was just pulling together links to some of my media appearances for a friend when I found one to the fall 2014 interview of yours truly by the inestimable Dr. Bill Bennett, when he still hosted his “Morning in America” radio show. It’s on the place of beheadings in Islamic doctrine and history, and whether ISIS was, and is, aberrant in its practice of decapitation. Here’s the link (I start at 28:17, after Hugh Hewitt’s intro).
