I Want a Life of Luxury!

How can a man be in prison but not be being punished? Welcome to the wacky world of the life sentence. My punishment ended 20 years ago. The past couple of decades of imprisonment were not meant to be punitive in any way. Life sentence are split into two parts. The first part is the 'tariff’ - the time to be served as punishment and retribution. In my case, ten years. According to the law, my debt is paid. Since then, 'post-tariff’, detention has been based on what it is believed I might possibly do in the future. It is preventative detention, not punitive. Please understand that I'm not offering an opinion, or throwing this open to debate -I'm stating the factual legal structure of life sentences, like it or not. So why shouldn't I have a TV, PlayStation, and hot-n-cold running women if I so desire? Why can I not have every amenity and luxury that I could afford, as long as it didn't undermine security? Sometimes it may be necessary to detain people after their tariff because they obviously pose a grave public danger. With proper legal safeguards, that may squeeze through the acceptability barrier. Just. But whilst we are being detained on such a basis, shouldn't the detainee be allowed all the amenities of a free man, save those that undermine security?
