I was a guest on the Bill Handel Show today discussing the libertarian perspective on blackmail, with reference to the Tiger Woods and other cases. (See my post Blackmail should be legal: the case of David Letterman.) We also touched on common law versus legislation (see my Legislation and Law in a Free Society), intellectual property, reputation rights and defamation law, prostitution, and extortion. Handel, though apparently not a libertarian, was a very smart and fair host. [For files, see the Kinsella on Liberty Podcast, Episode 32]. It it will be up later on the Bill Handel Show podcast.
