William O. Douglas,
Ex parte Endo — Opinion of the Court
“ Loyalty is a matter of the heart and mind not of race, creed, or color. He who is loyal is by definition not a spy or a saboteur. When the power to detain is derived from the power to protect the war effort against espionage and sabotage, detention which has no relationship to that objective is unauthorized.Nor may the power to detain an admittedly loyal citizen or to grant him a conditional release be implied as a useful or convenient step in the evacuation program, whatever authority might be implied in case of those whose loyalty was not conceded or established. ”
