The Ku Klux Klan held a peaceful rally Saturday to protest alleged unfair treatment of white students at a high school that selected a black valedictorian over a white classmate with better grades.

A heavy rain dampened the rally and the turnout was light, authorities said. It was closely patrolled by deputy sheriffs and agents of the Georgia Bureau of Investigation. There were no incidents.After the rally in the town square, the Klansmen moved away from the area onto nearby private property.

About 20 to 30 white students demonstrated Friday outside the Newton County High School, beset by racial tensions for several months. Sheriff's deputies and GBI agents stood by to maintain order. There were no incidents.

Student John Armstrong, 17, addressed the students over a loudspeaker as Keith Smith, imperial wizard of the U.S. Klan, Knights of the Ku Klux Klan, looked on. Some of the students were wearing "K-K-K" T-shirts.
