Read the passage.In 1965, a group of students in Des Moines, Iowa, wore black armbands to school to protest US involvement in the Vietnam War. School officials punished them by sending them home. The students’ parents sued the school for violating the students’ First Amendment rights, and the case eventually reached the US Supreme Court as Tinker v. Des Moines. In the court’s 7–2 majority decision, Justice Abe Fortas wrote:School officials do not possess absolute authority over their students. Students in school as well as out of school are "persons” under our Constitution. They are possessed of fundamental rights which the State must respect, just as they themselves must respect their obligations to the State. In our system, students may not be regarded as closed-circuit recipients of only that which the State chooses to communicate. They may not be confined to the expression of those sentiments that are officially approved. In the absence of a specific showing of constitutionally valid reasons to regulate their speech, students are entitled to freedom of expression of their views.
