Read this passage from Tinker v. Des Moines Independent Community School District. What is the main purpose of this section of the document?
The school officials banned and sought to punish for a silent,
passive expression of opinion, unaccompanied by any disorder or
disturbance on the part of petitioners. There is here no evidence
whatever of petitioners' interference, actual or nascent, with the
schools' work or of collision with the rights of other students to
be secure and to be let alone. Accordingly, this case does not
concern speech or action that intrudes upon the work of the
schools or the rights of other students.
A. To explain the school's complaints against the students
B. To redefine the amendment dealing with freedom of speech
C. To point out that the school officials were not justified in their
accusations toward the students
D. To explain how silent protests don't fall under freedom of speech
protection because no words are used
