" When a man is suffering from an infectious disease, he is a danger to the community, and it is necessary to restrict his liberty of movement. But no one associates any idea of guilt with such a situation. On the contrary, he is an object of commiseration to his friends. Such steps as science recommends are taken to cure him of his disease, and he submits as a rule without reluctance to the curtailment of liberty involved meanwhile. The same method in spirit ought to be shown in the treatment of what is called "crime. "
