Mahmut Karaduman was a Turkish national and the plaintiff in a famous libel case. The Long Island newspaper Newsday wrote a series of thirty-two articles entitled The Heroin Trail, which was awarded the Pulitzer Prize Gold Medal for public service. Karaduman sued Newsday over the following description: Bob Greene, Les Payne and Knut Royce were the Newsday journalists Karaduman sued. Although Karaduman was cleared of the drug charge in that there had been proven "substantial falsity" in the stories, there was no judgment against Newsday in that the story had not been grossly irresponsible.
