David, a high school student, wore a shirt to school that expressed his admiration for the United States Marines and for U.S. troops serving overseas. The t-shirt depicted a picture of an M16 rifle (the standard Marine weapon) between two stanzas of the Creed of the U.S. Marine, which includes the following language: “My rifle, without me, is useless. Without my rifle, I am useless.…I must shoot straighter than my enemy who is trying to kill me. I must shoot him before he shoots me.” Beneath the text is the seal of the Marines. When a school administrator observed David in the lunchroom, he asked David to change the shirt or turn it inside out, but David refused. The administrator threatened David with suspension and told him not to wear it again. The administrator’s objection was based on that portion of the school dress code that prohibits students from wearing “apparel depicting… symbols of violence.” The next day, David once again wore the shirt to school and was suspended. In response, David brought this suit against the school board and various school officials seeking an injunction that would allow him to wear the shirt to school. What factors will the court consider in deciding this case? How do you think the court will rule and why?
