This is where a group of students agreed to wear black arm bands to show support of the Vietnam truce in Dec. 1965, Des Moines, Iowa.
The Principal found out about this on December 14th and said they will be sent home if they do wear the black arm bands.
The kids still wore the bands to school, and was sent home from the school on Dec. 16th, 1965
The parent's of Mary Beth Tinker and Christopher Eckhardt tried to sue the school for violating the student's right of expression
The Supreme Court ruled that the school was in the rights when sending the kids home when the school defended that they were scared that the kids would disrupt the education.
The Judges said that the students don't lose their right to free speech, so the school has to provide ample evidence that the student is disrupting others from their education before suppressing their first amendment.
