A federal appeals court panel has ruled in favor of a Tennessee school system that banned clothing that displayed the Confederate battle flag. William Blount High School in Maryville, about 15 miles south of Knoxville, invoked the ban because of concerns the symbol could inflame racial tensions at a high school. Three students their parents argued in a lawsuit that the ban infringed on their free speech rights. The 6th U.S. Circuit Court of Appeals cited earlier race-related incidents at the school in ruling that officials had a right to ban the flag because they could "reasonably forecast" that it would cause disruption.
