The undergraduate heads of Naval and Military Science, in a letter printed on this page, condemn as un-American the recent picketing and baiting of supposedly interventionist lecturers. Some of these demonstrations may have been in poor taste, and may have provoked only vituperation or sulking from those at whom they were aimed. But there is no justification for saying that organized efforts for peace are out of place in America, or in this University. It is still legal to oppose the national defense program, the ROTC, the CAA, or pro-Allied sentiment. It is still legal to express such opposition in any way compatible with public order. To call these expressions un-American may also still be legal, but is in our opinion incorrect.
