I worked in corrections for a good while. I was a Housing Sgt for 3 years. Some are reformed by just being in the joint and others are not. It's always been this way. Those that want to change will change and those that don't want to change won't. I do believe that you could change most if you break their will to do things that are against the laws.
I would love to be a warden of a prison and run it the way I want to run it. The cells would be 4' by 7' stainless steel with a stainless bed being 2' wide. There would be a stainless basin for washing in and a stainless steel toilet that flushed once a week. There is a small drain in the floor to let any water in the cell out.
You would get a suicide blanket and underwear. You won't need anything else because you won't be going anywhere else in the facility to use it.
Each inmate is on 24/7 lockdown.
All three meals would be Bologna sandwiches. Might have a fruit and a vegetable for dinner, but it would be the same fruit and same vegetable each day.
There would be no contact with other inmates..... in fact you won't be able to hear or see other inmates. Contact with officers is very limited.
There would be no commissary.
There would be no mail call, no writing letters home.... in fact there would be no form of entertainment in the facility or any contact with the outside world.
There would be no greviences.
If you should happen to find a way to break any of the rules, you and your cell will get sprayed down with water. I just hope you like sleeping with a wet blanket and no way to dry off. Probably going to get cold since there will not be any heat pumped into the cells.
There would be no rec call, school call, or any other kind of call. Medical would be a privledge and if abused would be taken away. If you broke a rule and was sprayed down with water and caught the flu or a cold from it, this is just part of your punishment and will have to suffer through it that is unless you die from it.
The full term will be served. No possibilty for parole.
Of course this would have to be in a perfect world to make something like this work. If it was a perfect world though we wouldn't need prisons.
