Anthony Kennedy,
Ward v. Rock Against Racism — Opinion of the Court
“ It is true that the city's sound technician theoretically possesses the power to shut off the volume for any particular performer, but that hardly distinguishes this regulatory scheme from any other; government will always possess the raw power to suppress speech through force, and indeed it was in part to avoid the necessity of exercising its power to "pull the plug" on the volume that the city adopted the sound-amplification guideline. ”
