The Columbus Day protests in Chicago had anarchists, socialists, communists...and a Marching Band! Chicago's public Morgan Park High School turned out its marching band to entertain and rally the #OccupyChicago protesters.

Even though the demonstration occurred on Columbus Day, a public holiday, the participation of the marching band may have violated Chicago Public School policy, which prevents the misappropriation of school board property in “prohibited political activity for the benefit of any campaign for elective office or any political organization.” “Prohibited political activity” is defined as “[p]reparing for, organizing, or participating in any political meeting, political rally, political demonstration, or other political event.”
