If you dont becomes the NHS's compliant puppet physically and mentally aka their idea of a typical model citizen, you never get let out.
Its beyond inhumane and healthy, but humans have had thousands of years domesticating different animals, breeding traits in and out, which can be and have been applied to humans.
The state, ie police and NHS can totally bypass the legal system and incarcerate people, in effect dissappearing them, unless the legal system allows this?!?
