The Fourteenth Amendment, as now applied to the States, protects the citizen against the State itself and all of its creatures — Boards of Education not excepted. These have, of course, important, delicate, and highly discretionary functions, but none that they may not perform within the limits of the Bill of Rights. That they are educating the young for citizenship is reason for scrupulous protection of Constitutional freedoms of the individual, if we are not to strangle the free mind at its source and teach youth to discount important principles of our government as mere platitudes. On the other hand, the Court has repeatedly emphasized the need for affirming the comprehensive authority of the States and of school officials, consistent with fundamental constitutional safeguards, to prescribe and control conduct in the schools. See Epperson v. Arkansas, supra, at 104; Meyer v. Nebraska, supra, at 402. Our problem lies in the area where students in the exercise of First Amendment rights collide with the rules of the school authorities. —Justice Abe Fortas Tinker v. Des Moines February 24, 1969
