Robert H. Jackson, Kovacs v. Cooper — Concurrence
“ I do not agree that, if we sustain regulations or prohibitions of sound trucks, they must therefore be valid if applied to other methods of 'communication of ideas.' The moving picture screen, the radio, the newspaper, the handbill, the sound truck and the street corner orator have differing natures, values, abuses and dangers. Each, in my view, is a law unto itself, and all we are dealing with now is the sound truck. ”
