I disagree. I think we give them the shittiest food we can get away with. High fat and sugar, no weights or activities. I'd like to see them get access to free tobacco and receive only basic medical care. Anything above that should have to be paid for by relatives if they want to. The goal is to get them to die early since housing cost tax payers an average of $40k per year per inmate.
When proven guilty of murder, rape, child molestation or have more than 5 felonies we should execute immediately.
