InMilkovich v. Lorain Journal, did the Supreme Court hold that there is an "opinion privilege" in addition to existing free speech protection under the First Amendment? If so, why?If not, did the court conclude that the First Amendment does not protect pure opinions from defamation claims? Why did the court ultimately hold that the First Amendment did not prohibit the application of the state's defamation law to the article about Milkovich, a high school wrestling coach?
