The document summarizes several Supreme Court rulings related to students' First Amendment rights in schools: 1) The Court ruled in favor of students wearing black armbands to protest war, saying students do not lose their constitutional rights at school. 2) The Court ruled in favor of a school administration punishing a student for using sexually-oriented jokes in a campaign speech, as obscenity is not protected speech. 3) The Court ruled 5-3 that school officials can censor student media to avoid topics deemed inappropriate, as long as the censorship relates to "legitimate pedagogical concerns."
