By and large, I would expect inmates to choose the closest prison to their family, regardless of quality metrics. What good does it do to know that some prison 2000 miles away has a really good meal program?
Considering most inmates do not have access to the internet, do you expect the state to publish these stats in good faith? Inmates to trust them? Or do they just subscribe to print editions of The New York Times?
I guess I'm not sure if you're speaking in hypothetical or talking about inmates today. As the article is on California I'm assuming we're both discussing USA.
