In 1969, Des Moines students who wore Vietnam war protest armbands had to remove them or face suspension.
One important detail in the argument of the Tinker case was that the students’ protest did not take the form of written expression, but instead used a symbol, black armbands to represent the Vietnam war.
The Supreme Court ruled that the armbands were a form of symbolic speech, which is protected by the First Amendment.
The first amendment states that U.S citizens have freedom of peaceful protest.
Students can peacefully protest as long as the protest isn’t potentially offending anyone.
