A New Yorker piece on blackmail and the David Letterman case shows how confused and fumbling are the attempts to justify blackmail law–the article quotes from various professors such as James Lindgren and Richard Epstein. None of their reasons are coherent. The article cites one proponent of blackmail legalization, Walter Block. Block has written several articles explaining why blackmail is not a genuine crime, including one co-authored with me. See the “Blackmail” section of his publications page.
