> If you can stop them from doing it again by locking them up in comfort for 10 years instead of discomfort for 20, then that is what we should do. You're never going to stop many of them from reoffending. Even the "best" rehabilitation programs have crime rates far above the general population. The additional 10 years is 10 more years where they can't hurt innocent people. The justice system exists for the benefit o…

By this logic we should just never release them. Should we keep the 80% that would not reoffend locked up to prevent the 20% that would from doing so? Should we increase the sentence from 10 to 20 years to make that ratio 60% to 40%? Then we preve…
