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.
According to this memo, what evidence did Principal Carter have that band t-shirts caused problems?

9. Exhibit C: Email to Principal Carter
Bob,
I made a quick run to the supply room between classes last hour. Almost didn’t make it back to start class in time because I had to break up an argument between a bunch of kids in the hall. It was about bands again. A few of them were wearing t-shirts from that concert all the kids were talking about Monday morning. I almost sent them to the office because I thought a fight was about to break out, but then they started laughing so I sent them to class instead. Thought you’d want to know.
