I agree with you Luckygirl that such treatment of prisoners is beneath a cultured society, which we all would like to think ours is.
It is even worse that people with mental health problems cannot get treatment.
Thank you for having the courage to mention these things.
IMO no-one, whatever crime they have committed, has the slightest chance of becoming a better human being while in prisons like those you name. If treatment, remedial classes and education was automatically part of a prison sentence, it might just do some good.
Unfair on the victim and all the law-abiding citizens who do not commit crime?
Perhaps. No-one with physical or mental health problems should be denied treatment, nor denied a good education, so obviously facilities made available to inmates in prison, must be available to the law-abiding citizen as well.
One of the prime objects of legal punishment is the prevention of a re-occurrence of the crime, either by the person who actually committed it, or by others who might get the same idea.
I hope neither a victim or any victim's family and friends could disagree with that point of view.
To be fair, much more help should be available for the victims of crime than is the case, at present.
But if crime is to be prevented, which it unfortunately never will entirely be, then the obvious place to start is with a reform of the current prison system.
