Yes, you can, if the the other person is a public figure: "Under the First Amendment of the United States Constitution, as set forth by the U.S. Supreme Court in the 1964 Case, New York Times v Sullivan, where a public figure attempts to bring an action for defamation, the public figure must prove an additional element: That the statement was made with "actual malice". In translation, that means that the person making the statement knew the statement to be false, or issued the statement with reckless disregard as to its truth." http://www.expertlaw.com/library/personal_injury/defamation.html http://www.expertlaw.com/library/personal_injury/defamation....
