A prosecutor got an award for defamation of character because a newspaper published a letter to the editor from someone the prosecutor was prosecuting.
This isn't my area of expertise, but I'd bet this goes away on appeal. It seems to me that a newspaper provides a forum for an assertion of the citizen who sends the letter. Since the assertion wasn't by an employee of the paper the action would seem to lie with the person making the assertion; of course, the person who made that assertion is probably litigation proof.
