Tinker+vs.+Des+Moines

It all started out when a group of students decided to wear arm bands to school. But soon after, the school banned the arm bands because it was supposedly disruptive. The three students wore them anyway to protest Vietnam war because it was against the Tinker's religion. The case went all the way to the Supreme Court and the Court ruled in favor of the students saying that their Fourteenth Amendment Rights did not "end at the school house gate". The activity, despite the schools argument that it was disruptive, was not. So in conclusion the students had the right to free speech even in school.
