That depends on how you organise your prison system. Some prison systems are extremely violent, some are not. Maybe you should learn from those who are not as violent.
Joe Arpaio keeps a smooth system - but without all the perks and amenities - and has a low turn around rate and low incidences of violence and other issues.
However, his model has yet to be followed and many claim it to be barbaric. . . .so obvious learning from working examples still doesn't make people happy about it.
After all the number of murderers is really small. Imprisoning them for as long as necessary for them to die a natural death or not pose a threat any more are negligible compared to many other posts on the budget.
If people in prison are having better material conditions than those outside, maybe it is not the prisons there are something wrong with but the conditions outside. Just a thought I had.
No, it's a problem on the inside AND it's also present on the outside.
The problem in this bracket of issues is that once the government becomes reponsible for an individual then that person MUST be given all the basics and cared for - in part because of liability issues, honestly.
Prisoner's have demoted theirselves to being children of the state.
