3. Exhibit A The Memo TO: Hamilton Middle School Students and Parents
FROM: Bob Carter, Principal
RE: Hamilton Middle School’s New T-shirt Policy
Last year, many teachers saw students arguing about different kinds of music. Most of these arguments were caused by t-shirts that displayed a musical group. A few of the arguments were heated, and one even delayed the start of class until a teacher stepped in to stop the discussion. As a result, students may no longer wear clothing that refers to a musical group. This includes band t-shirts.  
The purpose of the new rule is to make sure the learning environment in our schools is safe and effective. We hope the new dress code policy will prevent more serious arguments or fights from breaking out in our schools.

5. Exhibit B The Letter Home Dear Mr. and Mrs. Brewer,
Today Ben came to school wearing a t-shirt showing the musical group “Hall of Rejects.” As you and Ben know, because of problems that began last year, Hamilton Middle School has adopted a new rule banning clothing that refers to musical groups. At lunchtime, a teacher noticed Ben wearing the shirt. The teacher told Ben to either turn his shirt inside-out or put on one of the shirts we keep in the office. However, Ben refused to obey. He insisted he had a right to wear the t-shirt.
Because Ben refused to follow the rules, I have placed him on in-school suspension for a week. I hope you will speak with Ben about what happened today and help him make more appropriate decisions about what he wears to school in the future.
  Sincerely,
Bob Carter
Principal, Hamilton Middle School
