Name a landmark Supreme Court case protecting freedom of speech.

• A. Roe v. Wade
• B. Marbury v. Madison
• C. Brandenburg v. Ohio (1971).
• D. Brown v. Board of Education

Answer: (C)

A central idea here is that speech is protected by the First Amendment unless it is aimed at producing imminent lawless action and is likely to do so. Brandenburg v. Ohio is the landmark case that clarifies this standard: the Court held that the speaker’s advocacy of violence at a rally did not itself constitute incitement because it was not directed at producing imminent unlawful action, nor was it likely to do so. This ruling makes it clear that protected speech can include provocative or controversial statements, as long as they don’t incite immediate illegal acts.

Why this fits as a landmark protection of speech is that it draws a precise line between expressing controversial or extreme views and actually pushing people to commit crimes right away. The other cases address different constitutional issues—Roe v. Wade deals with abortion rights, Marbury v. Madison with judicial review, and Brown v. Board of Education with desegregation. None of them establish the specific incitement standard that Brandenburg does for freedom of speech.
