They are unfit to be at liberty without supervision, because they are not capable of self-control; but many of them could be trained in the habit. At present they are allowed to run wild for a time and then severely put down. Their life alternates between periods of riot and periods of repression, and their natural unsteadiness is intensified. If they knew that the period of riot had definitely ceased--that they were not again to be allowed to do what they liked if it implied harm to others--they would set about to control the temper that is in danger of finally controlling them. They boast of being able to stand our punishments, and even invite them; they might as easily be trained to qualify for our rewards had we any to offer. They may be brutal and sometimes are, though brutality is no longer a common characteristic of prisoners in prison; but it does not follow that, bad as some of them may appear, they are incorrigible. Their conduct and reputation make it difficult to obtain guardianship for them. What can be done with them? If they are liberated at any time they are a menace to the safety and the comfort of the citizens. It is because some writers have recognised this that they suggest the lethal chamber as a suitable place for them. It is a bold thing to propose the wholesale killing of other people except in name of war, and if there were any danger of the proposal being adopted it is not at all likely that it would be made. It is designed to shock us, and it fails to do so because we think we know that it will not bear discussion. As a matter of fact, at present we destroy the lives of these people in another way. Instead of curing them of their evil propensities we twist them still further, and kill any sense of public spirit in them as effectively in the process as we could do if we suffocated them. If they were put in the lethal chamber that would be an end to them. As it is, we have to set apart respectable citizens, not to make them better, but simply to watch them marking time before engaging in another period of disturbance. If they are not killed they must be kept. We have got past the killing stage. It is time we adopted a more rational way of keeping them. Either they have to get out some day, or they have to be imprisoned till their death. In the latter case we need not trouble about them beyond seeing that they are not harshly treated, and that those over them do not develop in some degree the qualities condemned in the prisoner; but if they have to come out again it behooves us to see that they are not set free in a condition that makes them less able to conform to our laws than they were when we took them in hand. Otherwise all we have gained by their incarceration is the privilege of keeping them at our expense.
