A) Free speech is guaranteed under the First Amendment without exception. INCORRECT This option is incorrect because the Supreme Court has consistently held that free speech is not absolute. In Schenck, the Court ruled that speech can be limited when it creates a clear and present danger. The First Amendment protects against government censorship, but it does not protect all forms of expression, such as incitement to violence, obscenity, or defamation. The Court's decision in Schenck explicitly rejected the idea of unlimited free speech, establishing that context matters in determining the level of protection.
B) Language that creates a clear and present danger is illegal. CORRECT This is the correct answer because the Supreme Court in Schenck v. United States established the 'clear and present danger' test. Justice Holmes wrote that speech which poses a clear and present danger to national security or public safety is not protected by the First Amendment. In this case, Schenck's leaflets urging resistance to the draft were deemed to create such a danger during wartime. This ruling allowed the government to restrict speech that could undermine the war effort, setting a precedent for balancing free speech against national security concerns.
C) Language that incites imminent lawless action is banned. INCORRECT This option refers to the standard established in Brandenburg v. Ohio (1969), which replaced the 'clear and present danger' test. The Brandenburg standard protects speech unless it is directed to inciting imminent lawless action and is likely to produce such action. This is a more speech-protective standard than the one applied in Schenck. While this option describes a valid legal principle, it is not the decision in Schenck, which used a looser standard that allowed restrictions on speech during wartime.
D) Free speech is violated by the Espionage and Sedition Acts. INCORRECT This option is incorrect because the Supreme Court upheld the constitutionality of the Espionage Act in Schenck. The Court did not find that the Act violated the First Amendment; rather, it ruled that Schenck's actions were not protected speech. The Espionage Act was used to prosecute individuals who interfered with military recruitment, and the Court determined that such interference could be criminalized. This decision affirmed the government's power to enact laws that protect national security, even if they restrict speech during wartime.
