If it is not totalitarian to arrest a man and detain him, when you cannot charge him with any offence against any written law – if that is not what we have always cried out against in Fascist states – then what is it?… If we are to survive as a free democracy, then we must be prepared, in principle, to concede to our enemies – even those who do not subscribe to our views – as much constitutional rights as you concede yourself.
Obviously, there are people who constrict themselves and build walls around themselves, whether it's from a moral standpoint or a patriotic standpoint, or just plain old conformity, and who therefore live in those little prisons, and when things breach those walls, it's shocking for them.
