Interesting Tinker issue:

A student has been banned from displaying the Confederate flag on his truck while on school grounds.

…

The school district called the flag offensive and said schools can limit students’ rights while they are on campus.

“It has been proven to be patently offensive to certain groups and the courts recognize that,” Dennis Runyan, superintendent for the Agua Fria Unified School District, told KSAZ. “Obviously there was some event that took place it was related to reaction to the flag and it did create an environment where it was disruptive.”
