Ah... well, at least that makes sense. Still, having a guaranteed meal and a guaranteed bed and a guaranteed place to go to the bathroom and exercise... the people that go to prison for those reasons should be the ones deprived of it. Here in San Diego, some guy walked into a store, told the man behind the cash register to hand over money, only took a $20 and then proceeded to sit and wait for the the cops to come. Something wrong there?
If you go to prison for a crime that is more than just an excuse for having a more comfortable life, and show that you don't want to be there, then amenities are fine. I can understand a person who made a bad mistake and now wants to get out of the gutter.
But I cannot understand allowing people who are repeat offenders to continue to live like other inmates. Why not make their life harder? Show them that life sucks, but if you keep on stealing, etc. then you aren't going to get anything nice. Solitary confinement comes to mind-- for people that cannot be trusted with the other, nicer, parts of the prison, allow them to sit and think about what they did in a room that is not pitch black, but just slightly dimmer than a normal room. Don't allow anyone to talk to them and keep it very quiet for them. Let them think. They may not like it, but after 72 hours you can get a lot of thinking done.
